A comparison of the X-ray line and continuum morphology of Cassiopeia A

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 poi nts 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 pre dominantly from the Western region, making this the most likely location fo r the hard X-ray tail seen with instruments on CGRO (OSSE), BeppoSAX (PDS) and RXTE (HEXTE).
