The detection of the Sc-44 nuclear de-excitation lines and hard X-ray emission from Cas A
Jacco Vink, J. Martin Laming
We discuss the detection of Sc-44 (product of Ti-44) in the supernova remnant Cas A with the BeppoSAX-PDS instrument, and elaborate on the nature of the hard X-ray continuum, which…

Non-thermal bremsstrahlung as the dominant hard X-ray continuum emission from the supernova remnant MSH14-63 (RCW 86)
Jacco Vink, Johan Bleeker, Jelle Kaastra +3
We present an analysis of the X-ray emission of the supernova remnant MSH14-63, which was partially covered by four observations with XMM-Newton. The detection of Fe K emission at…

A synoptic spectral study of Cassiopeia-A based on XMM-Newton and BeppoSax observations
Johan Bleeker, Jacco Vink, Kurt van der Heyden +3
In this paper we present recent image and spectral data of Cas-A obtained with XMM-Newton and BeppoSAX. Analysis of the hard X-ray continuum does not support an interpretation of t…
