A comparison of the X-ray line and continuum morphology of Cassiopeia A
Abstract
We present deconvolved narrow band images of Cas A as observed by the MECS instrument on the BeppoSAX X-ray satellite. The images show that Cas A has different morphologies in the continuum and line bands. This difference points towards a synchrotron origin for part of the X-ray continuum of Cas A. Going to the hardest continuum band we find that the emission is coming predominantly from the Western region, making this the most likely location for the hard X-ray tail seen with instruments on CGRO (OSSE), BeppoSAX (PDS) and RXTE (HEXTE).
