Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION
WHAT IS THE EXTENT OF IC 443'S HARD EMISSION?
ABSTRACTWe have discovered two regions of hard X-ray emission in the supernova remnant IC 443, coinciding with where its radio-bright shell overlaps a ring of molecular clouds. We have argued that the X-rays from these features are synchrotron emission from cosmic ray electrons with energies of ~10 TeV. Unfortunately, these hard features were at the edge of the ASCA GIS field of view during the previous observation, and appear to extend beyond it. We propose a 40 ks observation primarily to determine whether the hard X-ray ridge encompasses the entire region of shock/cloud interaction. In addition we will obtain the first SIS spectrum of the known hard X-ray regions.
