Study of MeV continuum from Cas A with COMPTEL
Supernova remnants are likely sources of cosmic rays. Energetic
particles accelerated in these objects should provide a variety of
continuum emission signatures over the entire electromagnetic
spectrum. Models predict that electron synchrotron emission may be
detected from radio to hard X-ray energies, while at higher energies, in
the MeV regime and above, the same electrons are expected to be visible
through bremsstrahlung. The hard X-ray continuum emission from the
Cas A supernova remnant indicates in fact the presence of high-energy electrons
and makes it an interesting candidate for study at MeV energies.
We have analysed COMPTEL data for evidence of continuum emission in
addition to the previously detected 44Ti line. The implications of the
results in constraining models of the emission will be discussed.
