Abstract (from CDS):

The COMPTEL instrument on CGRO has surveyed the entire sky in the energy range of 0.75-30MeV. These data provide the first opportunity to perform a systematic all-sky search for MeV emission from Galactic black hole candidates. The COMPTEL team has previously reported on the positive detection of both Cyg X-1 and GRO J0422+32 at energies up to ∼2MeV. The spectrum of Cyg X-1 as measured by COMPTEL suggests that there may exist an additional component other than that produced by Comptonization of thermal electrons. The various possible black hole emission mechanisms of particular interest in the COMPTEL energy range are described and the status on the search for these emissions from all known Galactic black hole candidates is reported.
