FAMILIES AND SCATTERING . ... An important observation on the orbital distribution of irregular satellites is that satellite families at Saturn, Uranus and Neptune are not well defined. At Jupiter one finds 3-4 reasonably compact retrograde families, corresponding to each of the previously known retrograde irregulars and one prograde family. ... That is contrary to the current doctrine that very little has happened to these irregular satellite families following their collisional formation. ...

... The GW from coalescing compact binaries composed of NS and BH are the best understood of all astrophysical GW sources. A conservative lower limit to the event rate of galactic binary neutron star coalescence of about 1 per 100000 year follows from double pulsar   statistics studies (Narayan et al. ... In Figure  47 we show the rates of coalescence of binary WD and NS in a model elliptical galaxy   consisting of stars, depending on time elapsed since the (assumed instantaneous) star formation. ...

The completion of the 12-mm and 3-mm receiver systems on the Compact Array has secured two new astronomical windows into the southern skies. ... These include investigating the molecular gas reservoirs in and around galaxies in the very distant (high redshift) universe. ... Northern hemisphere millimetre interferometers have already observed molecular gas and dust in a handful of high-redshift radio galaxies, confirming that these objects are still forming the bulk of their stars. ...

... Ultra-compact dwarf galaxies (UCDs): . ... UCDs are characterised by old stellar populations, are larger, brighter and more massive than the biggest Milky Way globular clusters (GCs), but at the same time significantly more compact than typical dwarf galaxies of comparable luminosity. ... UCDs are remnant nuclei of tidally stripped dwarf galaxies ( Bassino et al. ... UCDs are genuine compact dwarf galaxies formed in the smallest peaks of primordial dark matter fluctuations ( Drinkwater et al. ...

... Астронет | ... Переменные Звезды | ... Микролинзирование . ... На протяжении последних нескольких лет в рамках проекта MACHO проводятся наблюдения микролинзирования звезд Большого Магелланова Облака - спутника нашей Галактики. Эффект микролинзирования заключается в гравитационной фокусировке света звезды массивным объектом, находящимся на луче зрения между звездой и наблюдателем. ... Согласно некоторым гипотезам, линзами могут являться реликтовые черные дыры или "нейтралинные звезды". ...

Time has come for me to move to a new longitude, but not before following the tradition and updating you on the work I have been doing in the latest stages of my PhD (and beyond). ... This presentation would of course not be complete without a final attempt at convincing you of the potential of some excitingly new technology to publish multi-dimensional datasets in 3-D. Hence, I shall also tell you about the newly developed X3D pathway Chris Owen and I have been developing lately. ...

... We report the results of a millimeter interferometric survey of compact 3 mm continuum sources in the inner 5.5'x5.5' region of the Serpens core. We detect 32 discrete sources above 4.0 mJy/beam, 21 of which are new detections at millimeter wavelengths. ... The mass spectrum of the clumps, dN/dM~M^(-2.1), is consistent with the stellar initial mass function, supporting the idea that the stellar masses in young clusters are determined by the fragmentation of turbulent cloud cores. ...

... The Workshop is dedicated to QCD Phase Transitions and observational signals of these Transitions related to formation of compact astrophysical objects. The aim of this workshop is to bring together researchers working on the problems of the behavior and observability of matter under critical conditions achievable in such astrophysical objects as 'strange' or 'hybrid' stars and in laboratories at heavy-ion collisions to discuss fundamental issues and recent developments. ...

... The formation of multiple images of a distant quasar by the gravitational lensing effect of a foreground galaxy may be very simply, and faithfully, accounted for by a wine glass experiment. Figure 1. In the wine glass experiment, a bright compact light source (at the top of the photo) serves as a distant quasar. The wine glass on the table distorts the light rays from the "quasar" and produces a caustic having with a triangular shape (see enlargement in Figure 3 ). ...
