| dc.description | 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 is not only important for correctly estimating the Sc-44 flux, but is interesting in its own right. We apply the lower hybrid wave electron acceleration model to the hard X-ray data and use upper limits on the cosmic ray injection spectrum to infer that B > 2 mG. We conclude with the prospects of observing nuclear decay lines and electron-positron annihilation in Cas A with INTEGRAL. | |
