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. ...

We report far-infrared and submillimeter observations of supernova 1987A, the star whose explosion was observed on 23 February 1987 in the Large Magellanic Cloud, a galaxy located 160,000 light years away. ... The intensity and spectral energy distribution of the emission suggest a dust mass of about 0.4 to 0.7 times the mass of the Sun. ... Our observations imply that supernovae can produce the large dust masses detected in young galaxies at very high redshifts. ... ADS Citation Query . ...

Here are two images of SN 1998ey in NGC 7080. The discovery image (Dec.5th) was stretched quite a lot and only just visible above the noise. It was a 30 sec. exposure with a 30cm f/6.3 SCT and Starlight Xpress ccd in bright Moonlight and mist. I was very lucky to have detected it under these conditons as it was at mag. 17.0 or a little fainter. ... Back to 1998ey .

. While studying the dust content of the Crab Nebula with the Herschel Space Observatory, astronomers have detected emission lines from argon hydride, a molecular ion containing the noble gas argon. This is the first detection of a noble-gas based compound in space. This image shows a composite view of the supernova remnant as viewed by the Herschel and the Hubble Space Telescope.

This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

Astronomers Detect Coolest Radio Star . ... The new radio-star is much smaller and colder than our Sun.€а With a surface temperature not much higher than that of a giant planet, and a size comparable to JupiterтАЩs, it is scarcely visible in optical light.€а Yet the radio flares seen at Arecibo show it must have a strong magnetic field, implying that the same could be true of other similar stars. ...

Next: Radiopulsars as Sources of Up: Cosmic Rays and Evolution Previous: Cosmic Rays and Evolution . Presently, there is little doubt that galactic CR can be generated at rapidly expanding shock fronts produced by supernova explosions. ... Statistical properties of radiopulsars in our Galaxy indicate a formation rate of NS of about 1 per 10-20 years in the present cosmological epoch, while direct astronomical observations have so far not detected supernova explosions at this high rate. ...
