Detected Supernovae . The search have produced till now the detections of 4 SNe. ... This result highlights the power of infrared monitoring in detecting Obscured SNe and indicates that optical surveys are probably missing a significant fraction of SNe, especially in obscured systems such as starburst galaxies. ... In Fig. we show the archival SOFI image of NGC3256 (left) and the first image obtained in 2001 (right) where SN2001db has been detected. ...

... Massive stars, having 10-150 masses of the Sun, with metallicities Z tens to hundreds times less than that of the Sun (Zo), are the main regulators of the galaxy formation and evolution processes in the early Universe. ... In this galaxy, using the 6 m BTA telescope, a new massive blue variable star with high luminosity (>=10 5 Sun's luminocities in visible light) was found. As far as its properties are concerned, this star falls into an LBV (Luminous Blue Variable) class of stars. ...

. 66%) of the extreme AGB stars are variable and only smaller fractions of carbon-rich (6.1%) and oxygen-rich (2.0%) stars are detected as variable sources. We also detect a population of variable young stellar object candidates. [ ADS ] . ADS Citation Query . # citations = 41 . citations vs. year [year,citations] .

A team of U.S. and German astrophysicists have made the first ever detection of X-rays coming from a comet. ... Following the initial detection, the team reported repeated X-ray emissions from the comet over the next 24 hours. ... One preliminary theory is that X-ray emission from the Sun was absorbed by a cloud of gaseous water molecules surrounding the nucleus of the comet, and then were re-emitted by the molecules in a process physicists call "fluorescence." ...

... For this paper: postscript PPEUC CMB index 1 Introduction.. ... We report on a 16 ks X-ray observation with the ROSAT PSPC towards the center of a CMB decrement detected by Jones et al. (1997) in the direction of the quasar pair PC1643+4631 A & B. At the position of the decrement we find no evidence for emission by hot gas which could give rise to the Sunyaev-Zel'dovich effect. ... We conclude that the CMB decrement is not a typical galaxy cluster. ... 2 The ROSAT PSPC observation . ...

... In the three intervening decades there have been many observations of this diffuse emission over a wide range of x-ray energies. ... During the 1970's researchers at the University of Wisconsin, lead by Dr. William Kraushaar, used a series of sounding rocket flights to map the diffuse x-ray emission from the sky in several bands. ...

These other worlds are the moons of our Solar System , of which there are approximately 170 in orbit around our planets.Some of these moons are very interesting, and have diverse and unique features, very different to our barren, heavily cratered Moon .Jupiter, the largest planet in our solar system has the most moons of any planet with known 64 moons in orbit.The four ...

... Programme . ... Its emission is detected from radio to -rays. Despite the fact that Centaurus A is one of the best studied extragalactic objects the origin of its hard X-ray and soft -ray emission is still poorly understood. ... A review of hard X-ray and -ray emission will be given (keV up to GeV) and the contribution of this observations to models of the Centaurus A emission wil be discssed. If no other talk addresses the newly reported emission > 250 GeV, this will be included.) . ...

... HD 10180: Richest Yet Planetary System Discovered . ... Our Solar System has the most planets of any known star, most probably because it is so hard to detect planets around other stars . Sensitive measurements, though, have now uncovered a slight but complex wobble of the Sun-like star HD 10180 indicating that it has at leave five planets and possibly more, making it the richest extra-solar planetary system yet known. ...

Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...

. In this review we discuss optical contiuum emission from stellar flares and the possible physical mechanism that may be responsible.

... A tussle in the distant Universe. This Hubble Space Telescope image shows evidence for a merger between a quasar and a companion galaxy. The quasar is the bright object just beneath the image center, and the wisps of material around it are remains of a galaxy disrupted by the interaction between it and the quasar. ...
