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. ...

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." ...

One of the goals of ALFALFA (the Arecibo Legacy Fast ALFA Survey) is that of verifying whether a significant population of optically faint, baryon rich, low mass systems exists. ... ALFALFA has easily detected the cloud VIRGOHI 21, reported by Davies et al. ... The clouds in the complex appear not to be gravitationally bound to one other, and may represent the remnant of an ancient episode of harassment. ...

... The SN 1998bv discovered on April 6, 1998 in the blue compact galaxy HS 1035+4758 is the second supernova observed in a low-mass galaxy with intense SF burst. ... According to its characteristic spectrum, SN 1998bv is a type II supernova with estimated peak absolute brightness M 16.3. The very slow fading of its brightness suggests that the SN was discovered at the Plateau phase, 20-30 days after the peak of the light curve. The most probable classification of SN 1998bv is regular SN II-P. 3. ...

Here we report our discovery of a band of blue luminescence (BL) in the Red Rectangle nebula. ... The spectrum of this newly discovered BL is most likely fluorescence from small neutral polycyclic aromatic hydrocarbon (PAH) molecules. ... If the carriers of this near-UV/blue fluorescence are PAHs, they are most likely neutral PAH molecules consisting of three to four aromatic rings such as anthracene (C14H10) and pyrene (C16H10). ...
