title={The space vacuum as the analog of the type I superconductor with respect to weakly interactions},
abstract={The last astronomical data do not let to doubt what the Universe is classified among the physical systems, the information\'s on which\'s it is impossible to consider the full one. It is precisely therefore the use of standard cosmological model, received within the scope of General Relativity adopting the deterministic conception, is the hindrance in the future researches. Specifically, it is necessary to return the original sense to the mathematical concepts such as the space curvature, which\'s must give the estimation of the physical reality rather than must replace it. We shall suppose that the greater part of weakly interacting particles constituting the great background of Universe exist in the degenerate (basic) state inserting the minor contribution in the vacuum polarization for the estimation of which the space curvature is used. Let as a result of some causes the disintegration of the Bose condensate will begin with formation of free fermions and with an increase of a pressure in some local area of Universe (it is possible which coincides with the metagalaxy). An inverse process of relaxation characterized by the formation of the Bose condensate and by the pressure decline should go with an energy release which will go on heating of the Fermi liquid with formation of excited states - of known charged fermions (quarks and leptons). Taking account of the negative result in experiments for the search of Higgs scalar bosons we suggest once again to be returned to the consideration of the mechanism to endow masses on particles. Considering the space vacuum as the analog of the type I superconductor we make the estimation of parameters characterizing the Cooper pairs of Universe weakly interacting particles.},

title={on the origin of annihilation emission from the Galactic center},
abstract={Both diffuse high energy gamma-rays and a strong and extended electron-positron
annihilation line emission have been observed in the Galactic Center (GC)
region. Although X-ray observations indicate that the galactic black hole Sgr
A is in inactive phase, we suggest that the Sgr A could still be the
energy source of the high energy emission. We argue that the galactic black
hole could be a powerful source of relativistic protons when it captures a
star. We assume that relativistic protons are injected into the
ambient material from the galactic black hole about hundred million years ago after
captured a massive star. In this way we are able to explain the current observed diffuse
gamma-rays and the annihilation line spectrum. Annihilation line is produced by secondary positrons whose time of cooling by Coulomb collisions is so large the the intensity of the annihilation line reaches its peak value long after the peak of high energy gamma-ray flux. The required
injected amount of energy is consistent with the estimation of the tidal
capture of a star by a massive black hole. The spatial distribution of the
annihilation intensity seems to suggest that there may be more than one stellar
capture event in the past.

indicates that a star with mass several $\\sim 10M_{\\odot}$ should be captured in
several million years ago and stars with typical mass several $\\sim M_{\\odot}$ should
be captured more frequently in a time scale of several hundred thousand years.
The capture of the lower mass star may be able to account for the recent TeV
observations within 10 pc of the galactic center. The spectral difference
between GeV flux and TeV flux could be explained naturally in this model as
well.

title={Strange star properties with a medium dependence in gluons at finite},
abstract={The possible existence of strange stars in the universe will help in the understanding of various properties of quantum chromodynamics, like asymptotic freedom and chiral symmetry restoration, which is otherwise very difficult to prove in laboratory experiments. Strange star properties are calculated using large color approximation with built-in chiral
symmetry restoration. A relativistic Hartree Fock calculation is performed using a modified and improved Richardson potential as an interquark interaction. This potential has the asymptotic freedom and a confinement-deconfinement mechanism built into it. The effect of temperature, on gluon mass in a simple way, in addition to the usual density dependence. We obtained a set of new equation of states for strange quark matter and also found that the transition temperature from hadronic matter to strange matter is at 80 MeV, close to the 100 MeV estimated in literature.},

Non classical Black Holes with
singularity horizon.

Israel Institution of Tech. aguidance@excite.com

We carefully analyze the apparently commonplace yet subtle concepts associated with the notion of existence of Black Holes. We point out that although the pioneering work of Oppenheimer and Snyder, technically, indicated the formation of an event horizon for a collapsing homogeneousdust ball of mass M in that the circumference radius the outermost surface,R→Rg=2GMRg/Rc²,it never explicitly showed the formation of aclassical trapped surface whith

C=R{ikml}R^{ikml}=12Rg}R^6,
but only nonclassical singularity trapped surface whith

C=R{ikml}R^{ikml}~12Rgδ(Rg-R)/R^6.

Irrespective of the gravitational collapse problem, by analyzing the properies of the Lemaitre and Kruskal transformations, in a straightforward manner, we show that finite mass classical Schwarzschild Black Holes with non singularity horizon can not exist at all.},

title={Envelopes of neutron stars with strong magnetic fields},
abstract={Neutron star crust and ocean provide thermal insulation
of the stellar interior and control thus the thermal evolution
of neutron stars, while the outermost surface layers, which can
be partially ionized, control the spectrum of emitted thermal radiation.
Strong magnetic fields can profoundly modify thermodynamic and
kinetic characteristics of matter (e.g., the equation of state and
radiative and thermal electron opacities) in the envelopes,
and thereby affect the link between stellar parameters and observations.
I review the theory of these effects, putting emphasis on
qualitative differences and theoretical problems brought about
by the superstrong magnetic fields of magnetars.

We describe the basic physical principles underlying the hypotheses
on the existence of strange quark matter or more exotic
forms of matter in the cores of compact stars or even at the
surfaces of these stars. We review then the main parameters of
hypothetical compact stars such as strange stars or even stranger
stars (particularly, Q-stars). We formulate observational tests
which would enable one to confirm or reject the hypotheses on
the existence of these objects and compare theoretical predictions

(Spitzer, NanÃay, Suzaku,...).
We report here the main results of these three years of
monitoring focusing
1) on the X-ray behaviour of the source as seen by INTEGRAL
and RXTE:
-class of variability
-long term evolution
-spectral and temporal properties, focusing on
some particularly interesting observations
2) The radio-X-ray connection:
-occurence of ejection of material
-correlation with the X-ray behaviour
Our monitoring shows the importance of long uninterrupted
exposures accompanied by multiwavelength coverage.
We discuss our findings in the context of accretion-ejection

title={Gamma Ray Bursts; An Historical Overview of its Origin },
abstract={
A History and overview of the origins of Gamma-ray bursts are presented.The phenomenon of Gamma Ray Bursts(GRB) are sudden releases of energy that in the space of a few seconds can outshine a huge galaxy of billions of stars, although they almost certainly come from a tiny region of space, infinitesimal compared to a galaxy. Till contemporary times, astronomers have debated where these bursts come from. Numerous theoretical physicists and astrophysicists have however debated with concrete explanations whether the bursts come from the local or \"galactic\"theory or from very distant space (the extragalactic or \"cosmological\" theory).
Some quarters propose the bursts come from small black holes or colliding neutron stars in young, faraway galaxies, other findings indicate they originate from the vicinity of giant, supermassive black holes in the centers of quasars or related objects. Moreover others even propose that some may come from \'evaporating\' black holes that may have existed shortly after the Big Bang. These are vital debateable theories proposed from miscellaneous institutions.

What then can cause GRB`S? It is however humbling to think that even
after 25 years and more than 3400 technical papers ,origins of
gamma-ray bursts is still a hot topic to be x-rayed.

title={Origin of the Galactic ridge X-ray emission: puzzle solved? },
abstract={Origin of the Galactic ridge X-ray emission (GRXE) was a long standing problem of X-ray astronomy. Explainations of the ridge emission by emission of a hot thermal plasma or by interaction of cosmic rays with interstellar matter were connected with serious problems. Latest studies of the ridge emission with highest sensitivity X-ray telescopes (like CHANDRA) have not provided conclusive answer. We have studied the morphology of the Galactic ridge X-ray emission with Rossi Explorer and showed that the GRXE contains both disk and bulge/bar components, which
parameters very well agree with those of known stellar Galactic components. We have showed that the GRXE volume emissivity well traces the stellar mass density in the Galaxy. Average Galactic unit stellar mass emissivity of the GRXE can be easily explained by average unit stellar mass X-ray emissivity in the Solar neighbourhood. Dominant contributors to the GRXE are accreting white dwarfs and coronally active stars. Weighted spectrum of known types of sources well agree with the spectrum of GRXE in the energy band 3-100 keV.},

SGR 1806-20, lying close to the Galactic Centre, and being very active in the past two years, has provided a wealth of new INTEGRAL results, which we will review here: more than 300 short bursts have been observed from this source and their characteristics have been studied with unprecedented sensitivity in the 15-200 keV range. A hardness-intensity anticorrelation within the bursts has been discovered and the overall Number-Intensity
distribution of the bursts has been determined. The increase of its explosive activity eventually led to the December 2004 Giant Flare for which a possible soft gamma-ray (>80 keV) early afterglow has been detected with INTEGRAL.

The deep observations allowed us to discover the persistent emission in hard X-rays (20-150 keV) from 1806-20 and 1900+14, the latter being in quiescent state, and to directly compare the spectral characteristics of all Magnetars (two SGRs and three Anomalous X-ray Pulsars) detected with INTEGRAL.},

A medium size satellite will be launched in the 2009-2010 timeframe into a 600 km equatorial (<4 deg.) orbit from Kourou or into a 29 deg. orbit from Baikonur as a fallback option. The payload includes eROSITA (extended ROentgen Survey with an Imaging Telescope Array, MPE, Germany) with 7 Wolter-type telescopes, the wide field X-ray monitor
Lobster (LU, UK), and ART telescopes (IKI, Russia). The mission will conduct the first all-sky survey with an imaging telescope in the 2-12 keV band to discover the hidden population of several hundred thousand obscured supermassive black holes and the first all-sky imaging X-ray time variability survey. In addition to the all-sky surveys it is foreseen to observe the extragalactic
sky with high sensitivity to detect 50 to 100 thousand clusters of galaxies and thereafter to do follow-up pointed observations of selected sources, in order to investigate the nature of Dark Matter and Dark Energy. The new SRG mission would thus be a highly significant scientific and technological step beyond
Chandra/XMM-Newton and would provide important and timely inputs for the next generation of
giant X-ray observatories like XEUS/Con-X planned for the 2015-2025 horizon.},

abstract={The annihilation of dark matter in the Galactic halo is enhanced due to the presence of small-scale dark matter clumps. It is described the formation and tidal destruction of small-scale dark matter clumps in the the standard cosmological scenario with an inflationary-produced primordial fluctuation spectrum and with a hierarchical clustering of small clumps into the larger ones. The small-scale clumps are efficiently disrupted at early stages of structure formation starting from the time of clump detachment from the universe expansion. Only a small fraction of these clumps, 0.1-0.5%, survives the stage of hierarchical clustering. The survived clumps can be further destructed in the galaxies by tidal interactions with stars in the Galactic bulge, disk and halo. The dominant contribution to the clump destruction is shown to be given by the collective gravitational field of the Galactic disc. The resulting enhancement (boost factor) of annihilation signal due to the halo clumpiness strongly depends on the primordial perturbation spectrum and varies in the range 10-100.},

We show that the linear caustic approximation frequently used for HAE analysis typically has an accuracy of ~20%. We also obtain modified formulae for amplification of a source image near a critical curve (next approximation in powers of source size).
We evaluate the GLS parameters from OGLE (Optical Gravitational Lens Experiment) photometric data on images of a quasar in GLS “Einstein Cross” during 1997-2005, using different brightness distributions. During that time at least four HAE’s had been observed by OGLE in this GLS. These observational data are compatible with the hypothesis of caustic fold crossing, but they do not allow to make a choice between different brightness profiles (only to estimate an upper bound of the minor semi axis in the elliptic source model).

title={Transport of positrons in the interstellar medium},
abstract={The spectral analysis of the positron-electron annihilation, based on measurements made with the spectrometer SPI of the INTEGRAL observatory, indicates that positrons annihilate mainly in the warm medium, including the warm ionized and the warm neutral medium (Churazov et al. 2005 ; Jean et al. 2006). In contrast, the high filling factor of the hot medium, in the central regions of the Galaxy, suggests an e+/e- annihilation taking place mainly in the hot medium. This difference can be explained if positrons propagate in the interstellar medium and can escape the hot medium (Jean et al. 2006). The transport of positrons is also comforted by the production processes producing high-energy positrons (>1 MeV) with long-lived times before annihilation, favorable to their diffusion. We then present the possible processes of transport for both cosmic-ray positrons, at high energy (E >> 1 MeV), and positrons produced by the beta+ decay of radioactive nuclei at lower energy (E ~ 1 MeV). We also describe the diffusive processes of positrons during their cooling phase and during their thermalized phase before they annihilate with electrons.},

abstract={INTEGRAL is finding large numbers of fast transients. We have shown that, at least, a significant fraction of them are associated with OB supergiants (SFXTs).
Our ongoing observational campaign on SFXTs with a range of space and ground telescopes, including the VLT, has allowed us to identify new counterparts and derive their astrophysical parameters.
We will present new data on the counterparts to SFXT and derive their distances and X-ray luminosities. With these new data we will be ready to start characterizing the class of SFXTs.},

title={The hard X-ray luminosity function of INTEGRAL detected AGN},
abstract={We have compiled a complete, significance limited sample based on ~25,000 square degrees to a limiting flux of 3E-11 ergs/cm**2/sec (~7,000 square degrees to a flux limit of 1E-11 ergs/cm**2/sec) in the 20-40 keV band with INTEGRAL. We have constructed a detailed exposure map to compensate for effects of non-uniform exposure. The flux-number relation is best described by a power-law with a slope of 1.66 +- 0.11.
We present the first luminosity function of AGN in the 20-40 keV energy range, based on 68 extragalactic objects detected by the imager IBIS/ISGRI on-board INTEGRAL. The luminosity function shows a smoothly connected two power-law form, with an index of gamma_1 = 0.9 below, and gamma_2 = 2.2 above the turn-over luminosity of Lx = 4.6E43 ergs/sec. The emissivity of all INTEGRAL AGNs per unit volume is W(> 1E41 ergs/sec) = 2.8E38 ergs/sec/Mpc**3. These results are consistent with those derived in the 2 - 20 keV energy band and do not show a significant contribution by Compton-thick objects. Because the sample used in this study is truly local (z = 0.022), only limited conclusions can be drawn for the evolution of AGNs in this energy band. But the objects explaining the peak in the cosmic X-ray background are likely to be either low luminosity AGN (Lx < 1E41 ergs/sec) or of other type, such as intermediate mass black holes, clusters, and star forming regions.

title={GRI: The Gamma-Ray Imager mission},
abstract={Observations of the gamma-ray sky reveal the most powerful sources and the most violent events in the Universe. While at lower wavebands the observed emission is generally dominated by thermal processes, the gamma-ray sky provides us with a view on the non-thermal Universe. Here particles are accelerated to extreme relativistic energies by mechanisms which are still poorly understood, and nuclear reactions are synthesizing the basic constituents of our world. Cosmic accelerators and cosmic explosions are
the major science themes that are addressed in the gamma-ray regime.

With the INTEGRAL observatory, ESA has provided a unique tool to the astronomical community and has put Europe in the lead in the field of gamma-ray astronomy. INTEGRAL provides an unprecedented survey of the soft gamma-ray sky, revealing hundreds of sources, new classes of objects,
extraordinary views of antimatter annihilation in our Galaxy, and fingerprints of recent nucleosynthesis processes.

While INTEGRAL has provided the global overview over the soft gamma-ray sky, there is a growing need to perform deeper, more focused investigations of gamma-ray sources. In soft X-rays a comparable step was taken going from the Einstein satellite to the XMM/Newton observatory. Technological advances in the past years in the domain of gamma-ray focusing using Laue diffraction and multilayer-coated mirror techniques have paved the way towards a gamma-ray mission, providing major improvements compared to past missions regarding sensitivity and angular resolution. Such a future Gamma-Ray Imager will allow to study particle acceleration processes and explosion physics in unprecedented detail, providing essential clues on the innermost nature of the most violent and most energetic processes in the Universe.

The prominent Gamma-Ray blazar 3C 279 was observed by INTEGRAL
in a ToO observation, triggered by an optical high-state,
for a total of 511 ksec between January 13 and 22, 2006 in
several pointings. Centered on the INTEGRAL observations,
a multifrequency campaign was organized, which yielded simultaneous
measurements in radio and mm-bands (e.g. Effelsberg,
Metsaehovi, IRAM), in near-IR and optical bands by a WEBT-campaign,
and in X-rays by Chandra and Swift.
The analysis of the multifrequency data is currently in progress.
We will present first results of this campaign, focusing
on the results of INTEGRAL in the hard X-ray band
and on the observed multifrequency spectrum. These 2006 high-state
results will be compared to the ones derived during an optical
low-state of 3C 279 in June 2003 (Collmar et al., 2004).
The implications on blazar physics will be discussed.

orbital hard X-ray periodicities.},
abstract={Results of long-term monitoring of SS433 by INTEGRAL in 2003-2005
are presented. Several new features of the observed precessional and
orbital light curve of SS433 are particulary discussed. The amplitude
(maximum to minimum flux ratio) of
the precessional light curve in 20-60 keV is found to be
4-8 (much higher than in the standard X-ray band 2-10 keV),
with the secondary maximum present. An orbital eclipse observed
around precessional phase 0 coincides with the optical one, while that
observed at the phase 0.22 is found to be shifted with respect to the
optical eclipse. These features are described by the geometrical model
with thick supercritical accretion disk and jet from the central source.
The analysis of the INTEGRAL data allows us to put constraints on
the parameters of SS433 and lends further support that SS433 is
a galactic microquasar with black hole.

The INTEGRAL sky maps were used for the simulations of the image reconstruction in the space experiment with a wide field (up to ~2 \\pi sr) coding mask telescope elaborated for the all-sky monitoring in gamma-rays (0.05-1.0 MeV). The experiment with such telescope will have angular resolution about 2-3 degrees. Such resolution is enough for the study of the galactic and extragalactic variable sources, transients and gamma-ray bursts in soft gamma rays. The sky maps calculated with the use of INTEGRAL sky maps allow us to estimate the final capabilities of the proposed experiment. One can also consider the expected observation conditions for each of the known galactic and extragalactic sources.},

The phase space of the search spans the energy range 20-8000 keV and line widths from 0-1000 keV (FWHM). It includes both diffuse and point-like emission. We have searched for variable emission on time scales down to ~ 1000 sec. Diffuse emission has been searched for on a range of different spatial scales from ~ 20 deg up to the entire Galactic Plane. Our search procedures were verified by the recovery of the known gamma-ray lines at 511 keV and 1809 keV at the appropriate intensities and significances. We find no evidence for any previously unknown gamma-ray lines. The upper limits range from a few x 10^-5 cm^-2 s^-1 $ to a few x 10^-2 cm^-2 s^-1 $ depending on line width, energy and exposure. },

title={Microquasars’ contribution to the galactic positron annihilation radiation},
abstract={Microquasars are – by definition – compact objects that frequently eject matter through their jets. Whether the jet content is leptonic or hadronic or a combination of both is, at present, uncertain and model-dependent. Assuming the jets are not purely hadronic, various models and methods allow one to estimate either the “typical” microquasar’s or the global galactic microquasar population’s positron emissivity and thus see whether such a population (currently estimated at ~ 100 in the Galaxy – Paredes 2005) would constitute a substantial contribution to the 511 keV annihilation flux measured by INTEGRAL/SPI and other instruments. Furthermore, one can attempt to compare the spatial distribution of Galactic microquasars (based on the scarce available data on the two dozen sources known today) and the spatial distribution of the annihilation flux as inferred by INTEGRAL/SPI.

We estimate the production rate of positrons in microquasars, both by simple energy considerations and in the framework of various proposed models. We find that the collective emissivity of the annihilation radiation produced by Galactic microquasars might constitute a substantial contribution to the annihilation flux measured by INTEGRAL/SPI. The spatial distribution of microquasars leads to a Bulge/Disk ratio that is somewhat smaller than the lower limit inferred from INTEGRAL/SPI data. We stress that these results, although encouraging, suffer from significant uncertainties in our present knowledge of microquasar properties and jet physics.

Assuming that microquasar jets do eject substantial quantities of positrons (see Guessoum, Jean, and Prantzos, this workshop), these systems would represent interesting annihilation point sources, for which we determine the resulting flux and the corresponding light curve, as well as the line\'s spectral profile. For these calculations, a detailed treatment of the physical processes undergone by the positrons in the atmosphere of the companion star is performed. We discuss the possibility of detection of such point sources by future instruments.},

title={Brightness temperature and circular polarisation in extra-galactic radio sources},
abstract={Many extra galactic radio sources show rapid variability, which implies very high brightness temperatures (TB) well over 10^12 K, and high degrees of circular polarisation (CP) at the percent level. These results are well over the limits imposed by standard synchrotron models that assume a power law electron distribution. We examined the synchrotron and inverse Compton radiation from a mono-energetic electron distribution. The model gives TB of 10^13 to 10^14 K for moderate (~10) Doppler boosting factors, together with intrinsic degrees of CP of 1 to a few percent. I will present the constraints on TB and degree of CP of this model, and the synchrotron and inverse Compton emission predicted by this model, which gives a spectrum proportional to frequency to the 1/3rd power between radio and infra-red frequencies, and in gamma-ray between MeV to GeV. I will show that an estimate of the gamma-ray flux using published observations is above the detection threshold of the instruments on board INTEGRAL.},

abstract={Accretion onto a neutron star surface results in very high temperatures. Collisions of nuclei under these conditions can free neutrons, and these free neutrons can potentially be captured by hydrogen nuclei, producing 2.223 MeV photons ([H(n,gamma)D]). In a binary system, the 2.223 MeV photons can produce narrow or broadened lines depending on the position of interactions. If the capture is on the neutron star surface, it will produce a redshifted and broadened line. We searched for such a line from the accreting neturon star system 4U 1820-30 to determine the gravitational red-shift. This information can constrain the equation of state of the neutron star directly. In this poster, we summarize our preliminary results on this search. },

A successful explanation of the observed distribution is offered by a model taking into account the dependence N(t) of the number of high mass X-ray binaries on time elapsed after the star formation event. Using archival optical observations of the Magellanic

title={polarization measurement of GRB 041219 with SPI},
abstract={Measuring the polarization of the prompt gamma-ray emission from GRBs can significantly improve our understanding of both the GRB emission mechanisms, as well as the underlying engine driving the explosion. We searched for polarization in the prompt gamma-ray emission of GRB 041219 with the SPI instrument on INTEGRAL. Using multiple-detector coincidence events in the 100–500 keV energy band, our analysis yields a polarization fraction from this GRB of 66 +- 21%. While statistically this measurement suggests a non-zero polarization,
we cannot strongly rule out the possibility that the measured modulation is dominated by instrumental systematics. Even though SPI observations of GRB 041219 do not significantly constrain GRB models, the measurement demonstrates the capability of SPI to measure polarization.},

Title: \"INTEGRAL/SPI view of the hard X/gamma ray emission of a sample of X-ray Binaries: hard tail extension and emission
processes associated\"

Authors: S. Deluit, L. Bouchet, E. Jourdain et al.

Abstract:
We present the results of our analysis of a sample of X-ray Binaries (XRBs) observed by the Spectrometer SPI on board INTEGRAL.
Most of X-ray binaries emits below 150-200 keV, the detection of a thermal cutoff suggesting a pure Thermal Comptonisation as the physical mecanism at the origin of their hard X ray emission.
However, only few satellites enabled to extend the analysis above 200 keV.
The large energy domain covered by SPI (20 keV-8 MeV) and its high spectral resolution allow us to perform deep analyses at higher energies.
Through spectro-temporal studies of a sample of XRBs with SPI, we are able to investigate the presence of an hard tail above 150-200 keV
and the emission processes associated to their hard X/gamma-ray emission.
We then present a preliminary comparison with SPI of the X/gamma characteristics of XRBs hosting a neutron star or a black hole.

===================
Title: \"INTEGRAL contribution to the AGNs study\"
Authors: S. Deluit, E. Jourdain, J. Malzac et al.

Abstract:
Through the study of several Active Galactic Nuclei (AGN) observed by INTEGRAL, we present a view of the IBIS and SPI contribution to the
understanding of such extragalactic compact objects.
ISGRI allows spectral (primary continuum, reflection, cutoff) and temporal (variability over short and long timescales) analyses of
their high energy emission.
The spectrometer SPI gives a continuous view of the X to gamma ray emission in order to investigate the presence of spectral signatures
(such cutoff or break) above 200 keV.
The ISGRI and SPI complementarity thus provides us a powerful tool to study the characteristics and the processes related to the hard X/gamma ray emission of a sample of AGN, we review the results obtained.

title={Observational constraints on the injection energies of positrons at the Galactic centre and status of the dark matter annihilation scenario.},
abstract={The positron annihilation line at 511 keV in the Galaxy has been observed by INTEGRAL/SPI for more than 3 years.

The spectrometer confirmed this annihilation takes place mainly in the Galactic bulge with an extension of 8 degrees FWHM and a line flux of 10**3 ph/cm**2/s, corresponding to about 10**43 positrons annihilating every second.

None of the classic astrophysical scenarii -- supernovae, black holes, hypernovae -- has yet been able to qualify as the source of the annihilating positrons, as they failed to account either for the flux or for the morphology of the emission.
Though new considerations about the transport of positrons between their production and their annihilation (Prantzos 2005) recently revived some of those hypotheses, more exotic sources of positrons such as those involving dark matter remain topical.

Before 2004, heavy dark matter particles had been excluded from the list of candidate sources of positrons because of the direct or indirect radiations incidental to the decay of the dark matter particle and to the positron production. Such radiations were incompatible with observations.

Boehm et al. (2004) suggested a new dark matter candidate in the form of a light particle (1-100 MeV), whose decay would not be accompanied by the emission of any radiation or particles other than positrons and electrons.
Since then, some authors tried to disallow this light dark matter scenario by modelling indirect radiations, such as internal bremsstrahlung (Beacom et al. 2005) and in-flight annihilation (Beacom & YÝksel 2005) and by comparing them to observations.

In this contribution, we will review the various observational constraints relative to energy losses by a positron during its thermalization phase through the ionisation, inverse Compton, bremsstrahlung, synchrotron, in-flight annihilation channels. We will discuss the detectability of these effects by INTEGRAL and other experiments, and their consequences on the possible injection energies of the positrons responsible for the 511 keV line and thus on the mass range of a potential dark matter candidate.

title={Lastest INTEGRAL results on hard X-ray characteristics of
Anomalous X-ray Pulsars},
abstract={One of the breakthrough discoveries with INTEGRAL is the detection of hard X-ray emission from Anomalous X-ray Pulsars (AXPs). Before the INTEGRAL era AXPs were known as soft X-ray pulsars which could be studied up to ~10 keV. This view has changed drastically since the discovery of hard X-ray emission (>10 keV) from three AXPs by INTEGRAL (Molkov et al. 2004, Revnivtsev et al. 2004 and den Hartog et al. 2004; 2006). Kuiper et al. (2004; 2006) discovered pulsed emission above 10 keV from four AXPs using RXTE (PCA and HEXTE) data. The power-law like spectra (20-150 keV) are very hard with photon indices <~1.0 and the derived luminosities are 2-3 orders of magnitude above the rotational energy losses.

The regular and long INTEGRAL observations of the Cassiopeia and Galactic-Center regions allow us to study the spectral and timing characteristics of several AXPs in these regions in great detail. In this talk we will present, 1) the most recent INTEGRAL results on the detected AXPs, 2) compare these with those from observations at radio, near infra red and optical wavelengths, and 3) confront proposed theoretical scenarios from the production of non-thermal emission in AXP magnetospheres with our observational results.

The stars considered were pure quark stars ( or strange stars ) and hybrid stars consisting of a quark matter core with a nuclear matter crust around. The observational consequences are affected very much by the features of the process of star restructuring, when phase transition occurs in the interior of a star. The detailed analysis of the parameters of calculated configurations, useful for comparison with neutron star observables, is carried out. Such comparison might help to test the used equations of state for superdense matter. Possible observational tests are discussed to distinguish between the ordinary neutron stars, strange stars and superdense hybrid stars.},

abstract={NEUTRON STAR DIBARYONS GENERATING GAMMA-RAY BURST
V.M. Skorkin
Institute for Nuclear Research of the Russian Academy of Sciences, Moscow, Russia

Gamma-ray bursts (GRB) are the most energetic phenomena that occur in the universe. GRBs has been identified as being cosmological in origin, a peak luminosity of more than 10^53 ergs per second [1]. One of the most popular models for GRBs is the merger of binary neutron stars. The gamma-ray radiation is most likely produced by ultra-relativistic particles electrons and protons that are accelerated in the shock waves.
Neutron stars exhibit conditions for generating gamma-ray bursts. The gamma-rays can be generated dibaryons (sixquark states) decay in neutron stars [2]. Neutron stars contain the mixture of neutrons, protons and quarks. Neutron stars exhibit conditions for formation dibaryons Neutron stars have high particle and energy density. Central particle density of the neutron star with mass of 1.4 Mo and radius R =10.5 km is about 0.7 fm-3 [3]. Energy density of the neutron is about 1.0 fm^-4 (200 MeV·fm^–3). Dibaryons can be generated at three-nucleon interaction in neutron star. Dibaryon decay into D -> gamma N N . The possibility of the existence sixquark states was predicted by QCD models. Dibaryon masses are 1900 –1950 MeV. Cross section of dibaryon formation is about 10^–3 fm2. Dibaryon lifetime is about 10^-16 - 10^-18 s.
Dibaryons can form dibaryon condensate because they are bosons. Dibaryons form dibaryons condensate at density n above 0.01 fm^–3 and energy density above 0.1 fm–4. Dibaryon generation probability exceed by its decay probability. Dibaryon decay into two nucleons and photon with energy 20-70 MeV. Gamma-rays with energy of the 70 MeV (wave-length - 3 fm.) can cause dibaryon condensate decay in range on the order 3 fm. The condensate decay result in gamma radiation in cone with angle 10^–18 sr (for condensate size 10 km). This cone contain 10^38 dibaryons. Decay of the result in radiation with energy on the order 10^34ergs. Gamma radiation time (~1s) result in fast rise time of gamma-ray bursts. Gamma radiation energy into 4pi angle is 10^53 ergs.
Gravity field of neutron star slows down the decay of the condensate (several
tens of percent). Peak in the extragalactic gamma-ray spectrum is observed below
70 MeV [4].

pulse followed by a 200 s period of quiescence, before the main emission interval consisting of 2 minute-long strong pulses. The main periods of emission and the overall burst were well fit by the Band model, with some evolution of the low energy photon index after the quiescent period. Due to the brightness of the burst, it was possible to obtain a limit on the percentage polarisation of the prompt emission detected by SPI.

title={Superorbital variability in Cyg X-1 galactic black hole source},
abstract={Authors: A. Ibragimov, A. Zdziarski and J. Poutanen

The well-known black hole source Cyg X-1 has been continiously observed by the RXTE satellite during last 10 years, that leads to very large amount of observed data. One of the particular observation properties of the source is the superorbital variability with the period of 152 days. This periodicity is believed to be caused by the disk precession, and our work aims to investigate this hypothesis. Using both phenomenological and physical approaches, we determin the physical and geometrical parameters (inclination and precession angles, the emission pattern) that reproduce the observed flux variations. Our main finding is that the orbital modulation amplitude apparently has a connection with the superorbital phase. This fact provides a strong support in favour of explanation of superorbital variations with changes in the source geometry.

several pulsars, including V0332+53 and 4U0115+63. In V0332+53 the
changes of the pulse profile near the cyclotron line are especially
drastic. We discuss these results and possible emission mechanisms in
terms of the theoretical models of accreting pulsars.},

\" Optical identifications of INTEGRAL/RXTE sources with 1.5-m optical telescope RTT150\"


We present the first results of a campaign to optically identify X-Ray sources
discovered in the all-sky surveys of the INTEGRAL and RXTE observatories.
Optical observations have been made with 1.5-m Russian-Turkish telescope equipped
with CCD-photometer and TFOSC instrument.
Among dozen fields with unidenfied sources we have found six earlier unknown nearby
active galactic nuclei (Z < 0.1) and two close binary systems - intermediate polars.
Main spectral parameters and physical properties of the new discovered sources are
discussed.

title={The converter acceleration mechanism and accompanying radiation in relativistic shocks or shear flows},
abstract={We review the problem of particle acceleration in
relativistic shocks or shear flows. We compare different
acceleration mechanisms and show that the converter mechanism,
suggested recently, is the least sensitive to the geometry of the
magnetic field in accelerators and can routinely operate up to
cosmic-ray energies close to the fundamental limit. The converter
mechanism utilizes multiple conversions of charged particles into
neutral ones (protons to neutrons and electrons/positrons to
photons) and back by means of photon-induced reactions or
inelastic nucleon-nucleon collisions. It works most efficiently in
relativistic shocks or shear flows under the conditions typical
for Active Galactic Nuclei, Gamma-Ray Bursts, and microquasars,
where it outperforms the standard diffusive shock acceleration.
The main advantages of the converter mechanism in such
environments are that it greatly diminishes particle losses
downstream and avoids the reduction in the energy gain factor,
which normally takes place due to highly collimated distribution
of accelerated particles. We also analyze the properties of
gamma-ray radiation, which accompanies acceleration of particles
via the converter mechanism and can provide an evidence for the
latter. In particular, we point out the fact that the opening
angle of the radiation beam-pattern is different at different
photon energies, which is relevant to the observability of the
cosmic-ray sources as well as to their timing properties. Various
consequences for observations are discussed.

title={The self-consistent current sheets and filaments in relativistic astrophysical jets},
abstract={We find analytically a continuous set of stationary current sheets and filaments in collisionless multi-component plasma using integrals of two-dimensional motion of particles in the self-consistent magnetic field. In our solutions, the magnetic energy density can be comparable to that of particles, and the spatial scale can be arbitrary compared to typical gyroradius of the particles. We consider the properties of newly found stationary solutions and their possible applications to analysis of magnetic field configurations emerging in relativistic astrophysical shocks and jets.
We use our results for interpretation of recent observations and numerical simulations. By choosing particular dependence of particle distribution function on the integrals of motion we are able to obtain various profiles of magnetic field and self-consistent current, including non-monotone. The obtained solutions describe much more general class of equilibrium configurations as compared to known generalizations of Harris current sheets. On this basis, we suggest a way to describe slow dynamics and filamentation of collisionless current configurations in AGNs, microquasars and GRB sources.

Ending 11 years of quiescence, the last giant outburst took place in May/June 2005, but the source was too close to the Sun to be observed by most satellites. A subsequent normal outburst took place in August 2005, which was observed in INTEGRAL and RXTE TOO observations.

title={Accreting X-ray pulsars observed with INTEGRAL},
abstract={We present an observational review of the transient and persistent accreting X-ray pulsars observed with INTEGRAL. Accreting X-ray
pulsars are among the brightest sources in the X-ray sky and are observed frequently by INTEGRAL and other X-ray missions. Nevertheless
they are still very enigmatic sources as fundamental questions on the X-ray production mechanism still remain largely unanswered. These questions are addressed by performing detailed temporal and spectral studies on a large sample of objects over a long time range.

Of vital importance is the study of cyclotron lines as they provide the only direct link to the magnetic field of the pulsar. While some
objects show cyclotron lines which are extremely stable with time and pulse phase, in other objects the lines depend strongly either on the pulse, the luminosity of the source, or both. Of special interest in any case are transient sources where it is possible to study the evolution of the cyclotron line, the temporal behavior, and the source in general from the onset until the end of the outburst
through a wide range of different luminosity states.

negligible. However, a new calculation of the interstellar radiation field consistent with multi-wavelength observations by DIRBE and FIRAS indicates that the Galactic interstellar radiation field is intense. We have made a calculation of the attenuation of very high
energy gamma rays in the Galaxy using this new interstellar radiation field which takes into account its nonuniform spatial and angular distributions. We find that the maximum attenuation occurs around 100 TeV at the level of about 25% for sources located at the Galactic center, within the energy range of the HESS instrument, and is important for both Galactic and extragalactic sources.},

abstract={We present the results of hard X-ray observations of the Be stars gamma Cassiopeiae and HD 110432 made with the INTEGRAL observatory. Both these stars are known, low-to-moderate luminosity X-ray sources. Gamma Cas has recently been shown to be part of a binary system with a 203.59 day orbital period. The secondary was shown to have a mass of ~1 solar mass, consistent with a white dwarf, a neutron star, or a normal late-type dwarf, however no orbital modulation of the X-ray intensity has been identified. This result has fueled debate as to whether the X-ray emission is due to accretion onto a compact companion or magnetic activity near the surface of the Be star. HD 110432 has been shown to have similar spectral properties to gamma Cas and it has been suggested that it is also a good candidate for a Be+WD binary system. We present IBIS/ISGRI and SPI hard X-ray spectra of these systems. We also calculate light curves in an effort to search for flares and long timescale flux variations. The results are compared with those of previous hard X-ray missions such as BeppoSAX and ASCA and conclusions are drawn as to the origins of the hard X-ray emission.},

abstract={We present a model of Fourier Power Density Spectrum (PDS) formation in accretion powered X-ray binary systems derived from the first principles of the diffusion theory. Timing properties are defined by diffusion propagation in a bounded medium.
The PDS continuum consists of two major components, presumably coming from an extended accretion disk and from the innermost part of the source (Compton cloud). The disk PDS component has a power law shape with index ~ -1.5 and dominated during the soft states of the system, while coronal component is roughly described by a zero-centered Lorentzian. The PDS spectral components have their corresponding components in energy spectrum, namely, thermal (directly observed accretion disk) and power law (disk emission Comptonized by the corona) components. We apply the model to the Integral and RXTE data from Cygnus X-1, which describes the data adequately throughout all spectral states of the source. We argue that timing properties of neutron star systems are dictated by the same physics and the same model can be applicable to these systems as well.

abstract={Recently the existence of a class of Supergiant Fast X-ray Transients (SFXTs) has been revealed through observations of their characteristic fast outbursts with rise times of a few minutes and durations of 3-8 hours. The few established members of this group have OB supergiant companions and show high and variable absorption columns. The best studied of these systems is XTE J1739-302 (see contributions by Smith et al. and Negueruela et al. for new results from X-ray and optical analyses).
In addition several SFXT candidates have been identified, especially by monitoring programs of the Galactic Plane with RXTE and INTEGRAL. Considering the low source duty cycle, these detections might indicate that SFXTs are a dominant class of high mass X-ray binaries. Here we present a study of three new candidate SFXTs that have been identified by classifying light curves obtained from regular RXTE PCA scans of the Galactic Center. All three sources have also been extensively monitored with INTEGRAL, especially within the Galactic Center Deep Exposure (GCDE) program. A companion study concentrates on their precise localization and soft X-ray components (see contribution by Smith et al.).},

title={MGGPOD Version 1.1: a Monte Carlo Suite for Gamma Ray Astronomy},
abstract={Intense and complex instrumental backgrounds, against which the much
smaller signals from celestial sources have to be discerned, are a
notorious problem for low and intermediate energy gamma-ray
astronomy. Therefore a detailed qualitative and quantitative
understanding of instrumental line and continuum backgrounds is
crucial for most stages of gamma-ray astronomy missions, ranging from
the design and development of new instrumentation through performance
prediction to data reduction. We announce the public release of
Version 1.1 of MGGPOD, a user-friendly suite of Monte Carlo codes
built around the widely used GEANT (Version 3.21) package, to simulate
ab initio the physical processes relevant for the production of
instrumental backgrounds. These include the build-up and delayed decay
of radioactive isotopes as well as the prompt de-excitation of excited
nuclei, both of which give rise to a plethora of instrumental
gamma-ray background lines in addition to continuum backgrounds. The
MGGPOD package and documentation are publicly available for download
from http://sigma-2.cesr.fr/spi/MGGPOD/. Improvements implemented
in Version 1.1 of the proven MGGPOD Monte Carlo suite include:
additional beam geometry and spectral options, capability of modelling
polarized photons, additional output formats suitable for event
reconstruction algorithms, and improved neutron interaction
cross sections.},

The prominent Gamma-Ray blazar 3C 279, an optically violently variable
(OVV) quasar, was observed by INTEGRAL during AO3 on several occasions:
in the observations of the so-called \"Deep Extragalactic Survey\", pointing
to the Virgo region of the sky. This survey was conducted during the
summer 2005 and winter 2005/2006 visibility period of the field in AO-3,
yielding a total exposure time of 1 Msec.
Currently we are analysing these INTEGRAL survey data with respect to
3C 279. We will present the hard X-ray behaviour (lightcurves, spectra)
of the blazar as observed by INTEGRAL. The results will be compared to
other high-energy measurements of the source, put in multifrequency
context, and finally discussed in the framework of current blazar models.},

between 2003 and 2005.},
abstract={3C 273 is a radio loud quasar, with a jet showing superluminal motion, discovered at the very beginning of quasar research. Being one of the brightest and nearest quasars, 3C 273
was intensively studied at different wavelengths. In this work we present the results of quasi simultaneous INTEGRAL and XMM-Newton monitoring of the quasar during the period of 2003 -- 2005, and test with its help different theoretical models.

During the time period under discussion 3C 273 had the lowest flux ever observed in the mm domain. Coordinated multi-wavelength
observations in June 2004 in X-rays, optical, infrared, millimeter and radio domains were used to identify and study spectral features usually hidden by the strong synchrotron emission.

powerful tool to probe into the intimacies of the most recent supernovae, known or obscured.

As a necessary first step in the study of supernova explosions from the 44Ti gamma-ray line emission, we present the results obtained
on Cassiopea A from about 4Ms of observation with INTEGRAL/SPI. The analyses of two of the three lines of the decay chain (at 78.4 and 1157.0 keV) will be reported, and their outcomes discussed in terms of constraints on the explosion scenario, consistency with previous detections (by CGRO and BeppoSax),and
prospects for the discovery of young SNR using 44Ti signals.},

abstract={A new design of particles (or quanta) flows counter is offering having large dynamic range, which relative registration error slightly vary depending on input flow intesity. Such counters belong to logarithmic class.
Unlike wide known structure of logarithmic counters based on rising binary recount coefficient, presented recount concept is defined by integer-valued recurring expression that is colligates recurring Fibonacci expression. That\'s why mentioned counter can be called «Fibonacci counter».
Analysis of relative Fibonacci counter precision have done in comparison with counter based on binary recount. It was shown that under count rates greater than 900 Fibonacci counter have more preferred characteristics, specifically for an ordinary binary counter example that approximate logarithmic counter by piecewise linear one using the same input impules count range 10 Giga counts.
We offer simple hardware design for Fibonacci counter made of basic logic elements. },

At the best case, the induced electric field is expected to reach $10^{13}$ to $10^{14}$ eV. A trial to detect non-thermal emission from a best candidate among WDs, AE Aquarii, was performed with the hard X-ray detector (HXD) on-board the fifth Japaneses X-ray satellite, Suzaku. Although the HXD has non imaging capability, the sensitivity in 10 -- 70 keV band reaches about $5 times 10^{-6}$ -- $10^{-5}$ photons/sec/cm2/keV level with only 100 ksec exposure. A marginal detection has been achieved with the HXD, and was separated from the thermal emission. If it is real, this must be a first case of a detection of non-thermal emission from WDs.},

abstract={The INTEGRAL satellite observed the Vela region in the X-ray and gamma-ray energy bands during 1.7 Ms between November and December 2005 in the context of an INTEGRAL open-time observation proposal.
We present first results of the data analysis, including in particular a spectral and temporal study of the eclipsing high-mass X-ray binary Vela X-1.
Thanks to this long-term observation we could update the system parameters and obtain new ephemeris. A precise orbital ephemeris is important for the study of this system, since it allows to determine detailed time-resolved
spectra during the eclipse ingress and egress phases in different energy bands, and to monitor details of the companion wind.
In addition we derived the time-averaged spectrum of the source, investigating
the presence of cyclotron resonant scattering features (CRSF). Orbital and pulse-phase resolved spectroscopy have been performed to understand the underlying physics of the high-energy emission.
We studied the variation of the pulse morphology with energy and time. At high energy the profile shows a primary and a secondary peak. Using a relativistic description of the polar-cap emission of the neutron star,
we fitted the double-peaked pulse profile in order to model the pulsed flux in energy and constrain the system geometry.

The importance of the Vela region as a nucleosynthesis laboratory is underlined by the presence of potential nucleosynthesis sites

COMPTEL observations have revealed 1.8 MeV gamma-ray emission from the Vela region at a level of 3.6 10$^{-5}$ ph/cm$^2$/s, yet the source of the emission has so far not been identified.
In this paper, we present results of our search for 26Al gamma-ray emission in the Vela region with the spectrometer SPI aboard INTEGRAL,

abstract={The X-ray observations have revealed that many microquasars and low-mass

resonant absorption from and iron and other abundant ions. XMM-Newton

blend together modifying the observed 1--10 keV continuum (also yielding the Fe xxv and Fe xxvi absorption lines). We present the
time-averaged INTEGRAL broadband spectra of the LMXB dipping sources 4U

title={SWIFT-XRT follow-up observations of INTEGRAL AGNs},
abstract={In its 5 years of life INTEGRAL has discovered a large number of new gamma-ray
sources. Thanks to the IBIS/ISGRI instrument capabilities there are,
up to now, 128 IGRI sources and only for a part of them there is a clear identification.
From this IGRI source sample we have extracted 37 objects which are identified with AGN (active galactic nuclei) or are
likely candidates. We have cross-correlated this set of AGN with the
recent Swift-XRT observations and we have found correspondence for one fourth of our sample.
Swift-XRT observations allow us to better define the source position for the
study of the possible counterpart at other wavelengths and also provide us
the soft X-ray spectrum of the sources.
In this work we present the preliminary results on broad band (XTE-ISGRI)
spectra of new AGN sources discovered by INTEGRAL.

Binary 4U 1636-53
observed by INTEGRAL and BeppoSAX satellites,
covering the energy range 0.1-150 keV.
We study the spectral behaviour separately
in three epochs.
1st and 2rd epoch show a continuum well described by a soft blackbody and Comptonized spectrum
with a spectral transition associated with changes in the Comptonizing electrons
and black body temperature.
In the 3rd epoch, a hard tail dominates the emission above 40 keV.
This INTEGRAL spectrum can be fitted as the sum of a power law with
photon index of 1.8,
a blackbody and a Comptonized component.
A comparison with hard tails detected in Z sources and some soft states of black hole
binaries suggests that a similar mechanism could originate these components
in black hole and neutron star systems.

title={First detection of Compton Reflection in the Low-Mass X-ray Binary 4U1705-44 with INTEGRAL},
abstract={We will present data from INTEGRAL and BeppoSAX satellites showing a pronounced spectral state transition of the neutron-star, atoll-type, low-mass X-ray binary 4U1705-44. Its energy spectrum in both states can be described as the sum of a blackbody, a 6.4-keV Fe line and a component due to thermal Comptonization. For the first time in this source, we find a strong signature of Compton reflection in the INTEGRAL hard state, appearing presumably from the accretion disk surface illuminated by the primary Comptonized spectrum. The blackbody component originates in the optically thick accretion disk and the neutron-star surface, and the harder Comptonized component arises from a hot inner flow with the seed photons coming from the accretion disk and/or the neutron-star surface. The spectral transitions of 4U1705-44 are shown to be associated with changes in the accretion rate, changing in turn the temperature of the Comptonizing electrons and the strength of Compton reflection. This can be theoretically explained in a model with a truncated outer accretion disk surrounding a hot inner flow, with the accretion rate determining the truncation radius.

title={A mini-state transition in Cygnus X-1 },
abstract={I will present the results of an INTEGRAL observation of Cygnus X-1 in an intermediate state. During our 4 days long observation, the source exhibited a strong variability. A principal component analysis demonstrates that most of this variability occurs through 2 independent modes. The first mode consists in changes in the overall luminosity on time scales of hours with almost constant spectra. We associate this mode to variations of the dissipation rate in the corona, possibly associated with magnetic flares. The second variability mode consists in a pivoting of the spectrum around 10 keV. It acts on a longer time-scale: initially soft, the spectrum hardens in the first part of the observation and then softens again. This pivoting pattern is strongly correlated with the radio (15 GHz) emission: radio fluxes are stronger when the INTEGRAL spectrum is harder. We propose that the pivoting mode represents a \'mini\' state transition from a nearly soft state to a nearly hard state, and back. This mini-transition would be caused by changes in the soft cooling photons flux in the hot comptonising plasma, associated with an increase of the temperature of the geometrical thin disc. This interpretation suggests that during state transitions the radio jet power anti-correlates with thermal disc emission while the comptonised hard X-ray flux seems to vary independently. Our results also indicate a radiatively inefficient accretion flow in the hard state.

title={Searching for Millisecond Flares in INTEGRAL GRBs},
abstract={Since the discovery of the cosmological origin of GRBs there has been growing interest in using these transient events to probe the Quantum Gravity energy scale in the range 10^16-10^19 GeV, up to the Planck mass scale. This energy scale can manifest itself through a modification in the electromagnetic radiation dispersion relation, specifically, an energy-dependence of the velocity of light.
To impose stringent limits on a possible modification of the dispersion relation, a flare within a GRB must be both short, and significant over a wide energy band to provide a sufficient baseline for determining dt/dE, the difference in the arrival times of photons of different energies.
We have searched INTEGRAL-observed GRBs for suitable flares, requiring a 5 sigma trigger on a 2ms, 10ms, or 100ms time scale using only photons above 1 MeV. This search has been made more difficult by false triggers from the SPI electronic noise component evident in single-event spectra at 1.4-1.6 MeV. We report on the status of our work.},

title={Fast X-ray transients observed with INTEGRAL},
abstract={During three and a half years of operation INTEGRAL discovered more than 100 new hard X-ray sources that significantly (by 40-50 percents) enlarges the amount of such sources detected in previous experiments. Although sources of different types are obviously present in this sample, two source populations certainly escape: the strongly absorbed sources (with a very low flux in the standard X-ray band that made them unobservable in
X-ray surveys) and the short-living transients appearing on the sky for only a few hours (that made them again very difficult for observations).

Outbursts of the latter sources are shorter than the viscous time scale (>1.4 days) characterizing the transfer of matter in the standard accretion disk (if the disk gets matter through the inner Lagrangian point). However, the viscous time scale could be shorter if the disk is formed from the companion stellar wind or if it is not formed at all. Recent optical identification of several fast transients with OB-supergiants supports such point of view.

In this report we describe properties of several fast transients discovered or detected during outbursts by INTEGRAL in course of its ultra-deep Open Program observations of the Galactic center field. We consider conditions for the accretion disk formation in these systems in sight of constraints following from the observations. We discuss mechanisms responsible for the outbursts, in particular, unsteady accretion from the clumpy
stellar wind, and propose as well a new reliable mechanism.},

title={INTEGRAL/IBIS observation of the Galactic ridge X-ray emission },
abstract={We present results of study of the Galactic ridge X-ray emission (GRXE) in hard X-rays performed with IBIS telescope aboard INTEGRAL. Imaging capabilities of coding aperture telescope make it possible to account for flux from bright Galactic point sources and wide field of view permits to collect large flux from underlying GRXE emission. Extensive study of the IBIS/ISGRI detector background allowed us to construct the model which predicts the detector count rate with ~1% accuracy in the energy band 17-60 keV. Derived longitude and latitude profiles of the ridge emission are in good agreement with Galactic distribution of stars obtained from infrared observations. This, along with obtained hard X-ray spectrum of the Galactic ridge emission strongly indicates its stellar origin which support findings of Revnivtsev et al. 2005. Derived unit stellar mass emissivity of the ridge in the energy band 17-60 keV ~1.0x10^27 agrees with that obtained for accreting magnetic white dwarf binaries - dominant contributors to the GRXE at these energies. At energies higher than 70--80 keV no additional contribution to the total emission of the Galaxy apart from detected point sources is detected.},

the tangent of the Sagittarius Arm, has been observed during 2003 by
the high energy observatory INTEGRAL. The field, centered on the position
of the X-ray burster X1916-053 contains three interesting objects.
One is the microquasar GRS 1915+105, clearly detected by IBIS on May 1, 2003
during an observation lasting ~14 ks. The
two other sources are the X-ray pulsars 4U 1901+03 and XTE J1855-026.
The former, a recurrent transient, is bright in the May 1 observation
at an intensity of ~110 mCrab in the 20-40 keV energy range. XTE J1855-026,
seen at the level of ~15 mCrab was also detected. This source, an eclipsing

title={Adding hard X-ray imaging capabilities to a Compton Telescope},
abstract={The efficiency of a Compton telescope operating in its \'imaging mode\', as well as its angular resolution, decrease rapidly with energy below a few hundred keV. The efficiency decrease is mainly due to the increasing photoabsorption cross sections at these energies. The average distance between interaction sites for Compton events decreases with photon energy; this, together with the increasing impact of Doppler broadening, results in the instrument\'s angular resolution rapidly deteriorating. These limitations of efficiency and angular resolution constitute essentially \"fundamental\"
limits on the energy regime accessible to imaging Compton telescopes.
At the same time, a Compton Telescope at balloon altitudes or in space is exposed to Cosmic diffuse and atmospheric photon backgrounds. The intensity of both of these components increases rapidly with decreasing energy, making photons < 100 keV a possibly significant contributor to random coincident events or instrument dead time. Thus shielding of low- energy photon components is desirable.
For the first balloon flight of the Nuclear Compton Telescope (NCT) we have simultaneously addressed these two concerns by enshrouding the top of the instrument in a tin shield (bottom had BGO shielding), with part of the shield having strategically placed holes - a 10% open coded aperture mask working up to several tens of keV in conjunction with the finely pixellated double-sided Ge strip detectors. We present pre-flight calibration results.

accretion onto supermassive black holes},
abstract={X-ray surveys are essential in studying the demography and cosmological evolution of AGN. Deep X-ray surveys have greatly improved our knowledge of AGN at z>0.3, but told us little about the low-z AGN population. There is also evidence that most AGN are strongly obscured at optical and soft X-ray wavelengths. To have an unbiased picture of the local AGN population, very large-area hard X-ray surveys are needed. We recently made a serendipitous survey of the high Galactic latitude sky at 3-20 keV with RXTE and are close to a completion of an all-sky survey with INTEGRAL at energies above 20 keV. We will compare the main results of these two surveys, including the AGN luminosity function and NH distribution.},

title={The \"Nuclear Pile\" GRB Model: Spectro-Temporal Properties of Prompt GRB Emission},
abstract={The \"Nuclear Pile\" is a GRB model that can provide the electrons necessary for the GRB emission as a result of a radiative instability effected through the proton-photon -- pair reaction. Under conditions similar to those of the criticality of a nuclear pile, the energy storred in relativistic protons can be released explosively to produce the prompt GRB emission. Because of the reaction threshold, the nuFnu spectra of the resulting radiation exhibit a peak at ~1 MeV in the lab frame, in agreement with GRB observations. We provide detailed spectra of the prompt emission as a function of time from optical to 1 TeV energies, which are in general agreement with those observed. We also discuss the transition from the prompt emission to the afterglow.},

title={GRMHD Simulations of Jet Formation by Using a Newly Developed GRMHD Code},
abstract={We have developed a new three dimensional general relativistic magnetohydrodynamic (GRMHD) code by using a conservative, high-resolution shock-capturing scheme. The numerical fluxes are calculated using the Harten, Lax & van Leer scheme. The flux-interpolated constrained transport scheme is used to maintain a divergence-free magnetic field. We describe code performance on various one dimensional test problems in both special and general relativity. We show the jet formations from a geometrically thin
accretion disk near a non-rotating and a rotating black hole. The simulation results show the jet formation in a same manner as previous simulations (magnetically-driven
and gas pressure-driven). The jets propagate outward with strongly twisted magnetic field. The simulations continue longer than those in previous simulations. We conclude that the newly developed GRMHD code is more robust than our previous GRMHD code.},

title={SPI Spectral Analsyis of Bright Gamma-Ray Bursts},
abstract={There have been a number of bright gamma-ray bursts that occurred within the SPI and IBIS FCFOV, which have sufficient counts for accurate spectral determination. Previous studies have utilized the IBIS/ISGRI detector almost exclusively, however, there are cases where the peak-energy (Epeak) may lie above the ~200 keV IBIS useful sensitivity range (e.g. GRB 031203) or the low-energy ISGRI count rates saturate (e.g. GRB 041219). There are also
incidences where the GRB has occurred outside of the ISGRI FCFOV, limiting subsequent analysis. In several cases, e.g. GRB 031203 and GRB 050502, a determination of Epeak is of particular interest, as they have some apparently anomalous properties (such as being outliers on the lag-luminosity diagram). We were thus motivated to explore methods for SPI event extraction, which can be used in conjunction with the standard ISDC software, to form time-windowed burst spectra. The resulting spectra, consisting of pre- and post-burst backgrounds (within a single SCW) from which
a net GRB spectrum is generated, anre then analyzed using the full SPI instrument response, i.e. including diagonal plus off-diagonal elements are included, for different degrees of mask shadowing. Model fitting can then be performed using the ususal forward-folding methods. We discuss present details of our method, and results on our analysis of a number of bright GRBs, such as GRB 021203, 041219, 050502, 021125, and 030131.},

title={First high energy study of the mysterious source 1E 1743.1-2843},
abstract={In the last years, the persistent source 1E 1743.1-2843, lying at few arcminutes from the Galactic Centre, has been observed above 2 keV by all instruments with X-ray imaging capability. Neither type-I X-ray bursts nor pulsations providing indication on the nature of the compact object have ever been detected.
Before the INTEGRAL satellite, the source was detected only up to 20 keV. In the framework of the IBIS telescope survey, the first detection at high energy (20-40 keV) was obtained. In previous works, it was stressed that a possible high energy emission could give further indications on the accreting object. We report on results obtained with the INTEGRAL/IBIS data collected during the period 2003-2005 and public XMM-Newton and Chandra X-ray observations. We present the temporal study in the 20-40 keV band showing a rather constant flux on few months time scale, as well as the first broad-band spectral study (2-70 keV) showing a steep power law (~3) as high energy component. Combining spectral parameters and discussion about the luminosity evaluations for different possible distances, our conclusions are in favour of a LMXB system with a neutron star at distance higher than the Galactic Centre, even though a firm conclusion can not be stated.},

multiwavelength approach allowed us to unveil the real nature of this
system. From radio wavelenghts to gamma-ray energies, we present a
complete analysis of the system which includes the detemination of the
nature of both, the optical and compact component, as well as the
properties of the mass transfer mechanism and constraints for the orbital
parameters of 4U 2206+54. From optical data (from on ground telescopes),
the spectral type of the optical companion, O9.5Vp, is derived. From
infrared and UV observations (from on ground telescopes and IUE,
respectively), the nature of the expanding envelope of BD+53 2790 is
analysed. From a combination of radio and high-energy observations (from
NRAO/VLA, INTEGRAL and RXTE), the nature of the compact companion, a
neutron star, is derived. Lately, using both high-energy light curves and
optical spectroscopy, the orbital parameters of the system can be
constrained.},

title={RHESSI instrumental limits on measurements of linear photon polarization from GRBs, SGRs and Solar Flares.},
abstract={The RHESSI spectrometer with its 9 large Ge detectors can be used as a rotating gamma ray polarimeter in the energy range from tens to hundreds keV. The polarization signal is extracted from the eventlist using Compton scattering technique in either single or coincidence mode. In an ideal case of low background levels and gamma source locations close to the satellite axis the modulation factor can be as high 50%. In this paper we discuss more realistic polarimetric performance of RHESSI using the entire satellite computer mass model and Monte Carlo simulations of photons reaching detectors also after scattering in the Earth atmosphere. In the single mode it introduces an additional, strongly oscillating background signal depending on relative position between the source, RHESSI and Earth. In the coincidence mode an extra contamination comes out from a position dependent pattern of accidental and real coincidences. New limits and examples of the minimum detectable polarization are given for several sources like Solar Flares, Soft Gamma Repeaters and Gamma Ray Bursts.},

title={GRB Observations with Suzaku Wideband All-sky Monitor},
abstract={The shield counters of Hard X-ray Detector onboard Suzaku are designed to use as the Wideband All-sky Monitor (WAM). The WAM is a very powerful Gamma-ray Burst monitor which covers the energy range between 50 keV and 5 MeV with large effective area of 400 cm^2 even at 1 MeV. The conjunctive observations with Swift Burst Alert Telescope, the WAM enable us to study the unbiased E_peak observation over the energy range of 15 keV to 5 MeV. The WAM has detected 45 GRBs coincident with the other satellites from 22 August 2005 through 15 January 2006. The detection rate is about 100 GRBs per year, which is consistent with our expectation before launch. So far, the WAM detected the gamma-ray emission up to 1 MeV from at least 8 GRBs including a bright and hard GRB 051008. In the conference, we present the new spectral properties of GRBs observed by the WAM.

We describe the implementation and initial results of the BAT
Slew Survey (BATSS) to derive BAT images for sky coverage in
slews to GRBs and pointed targets. Some ~40 slews (~2-3min each)
per day are obtained which significantly increase the BAT sky coverage
and allow an ASM-like capability for bright transients as well as
extend sky coverage for GRBs. The imaging software is nearly developed
and production processing of slew data, which have been acquired since
February, 2006, should be possible beginning in April. Initial
sky survey results will be reported, along with implications of
BATSS as a testbed for the scanning coded aperture survey proposed
for EXIST as the Black Hole Finder Probe.},

title={Hard X-ray view from initial half year observations of Suzaku},
abstract={Suzaku satellite, launched into orbit at 10th July 2005,
is equipped with four X-ray CCD cameras (XISs) combined
with X-ray mirror optics (XRTs) covering 0.3-12 keV,
as well as a hard X-ray detector (HXD) covering 10-600 keV.
The HXD is characterized with the lowest detector background ever achieved,
e.g. several times 10**-5 cts/s/cm2/keV at 10-50 keV and
the XISs also show more stable and lower detector background
in comparison with contemporary CCD detectors.
Together with its wide band-pass from 0.3 to several hundred keV,
Suzaku is a powerful tool to explore the high energy universe and its non thermal phenomena.
Within the first half year, Suzaku has observed more than 100 sources,
such as binaries, SNRs, Galactic center region, AGNs, galaxies and clusters of galaxies.
Some of the major hard X-ray results are provided in other talks,
while this talk will mainly present the in orbit performance
and characteristics of Suzaku as a hard X-ray observatory.
Brief summary of initial scientific results will also be presented.

emission of relativistic astrophysical jets associated with an exchange of interacting
high-energy photons between the jet and external environment. Physical processes
playing the main role in this mechanism are electron-positron pair production by
photons and the inverse Compton scattering. This scenario has been studied with
numerical simulations demonstrating that under reasonable conditions it has a
supercritical character: the high-energy photons breed exponentially being fed
directly by the bulk kinetic energy of the jet. Eventually particles feed back
on the fluid dynamics and the jet partially decelerates.
As a result, a significant fraction (at least 10--20 per cent)
of the jet kinetic energy is converted into radiation.},

We will present the results of a detailed imaging, timing and spectral analysis from the soft to the hard X-rays of Cygnus X-3, using the three high-energy instruments on-board INTEGRAL. The INTEGRAL data cover about 100 orbital cycles (4.8 h) of the system.

Cygnus X-3 has been observed from the early times of the X-ray astronomy, but its nature is still unknown. This work will give new clues to solve the mysterious nature of the system.

The analysis reveals changes in the spectral state of the source from high/soft to low/hard states. Moreover, during the high/soft state, the source presents orbital phase variability. This variability is characterized by a hardening of the spectrum when the source luminosity decreases.},

it can be well approximated by a simple powerlaw with a photon index of ~2. The contamination of the Galactic ridge emission to the PCA data was took into account.
