Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION
THE X-RAY SPECTRUM OF OLD SHELLS FEEDED BY POWERFUL ENGINES
ABSTRACT
We propose to observe the shells of two old SNR's: CTB 80 containing the 40 millisecond pulsar, PSR 1951+32; and W50 containing the jet source, SS433. While the X-ray spectrum from these shells is poorly measured with ROSAT, the broadband coverage of ASCA combined with its high spectral resolution will allow us to test for the thermal nature of the spectrum by detection of emission lines. The spatially resolved spectroscopy will also enable us to localize possible regions of non-thermal X-ray emission, whose evidence exists from the combined radio and X-ray morphology. Determining whether the spectrum is entirely thermal or not will allow us to 1) probe the energies dumped in the remnants and 2) test for cosmic ray acceleration in old rejuvinated shells.
