Session 44 - New Light on Supernova Remnants.
Display session, Wednesday, June 11
South Main Hall,
We present a new, deep (232 ks) ROSAT HRI exposure of Cas-A. This is the first X-ray image with enough photons to measure the outer, low surface brightness, shell of emission seen in the radio band. In addition 5 iterations of the Lucy-Richardson algorithm were used to deconvolve out the wings of the X-ray mirror point spread function, thus creating a image with a ``restored beam'' of 2.2" FWHM. These new data show a striking resemblance to the VLA radio continuum outside of the main shell. They clearly show the northern and southwestern radio features and the eastern jet region.
