Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION
OBSERVATIONS OF SN1993J
ABSTRACT
SN 1993J is one of five recent supernova explosions (SNe) detected in X-rays. It is observationally unprecedented, in that it is the only SNe detected in the radio and in X-rays within a week of the explosion, and whose X-ray light curve and spectral evolution have been carefully measured for over one year. We detected X-ray intensity variations in last one year, which is faster than we expect from a shock heating models. Thus, continuous monitoring is urged. We also expect to detect emission from a pulsar, if it is as bright as Crab pulsar.
