MeV Gamma-Ray Source Contribution to the Inner Galactic Diffuse Emission.
TSUJI N., INOUE Y., YONEDA H., MUKHERJEE R. and ODAKA H.
Abstract (from CDS):
The origin of the inner Galactic emission, measured by COMPTEL with a flux of ∼10–2 MeV cm–2 s–1 sr–1 in the 1-30 MeV energy range from the inner Galactic region, has remained unsettled since its discovery. In this paper, we elaborate on a model of individual MeV gamma-ray sources unresolved by COMPTEL. This is conducted for sources crossmatched between the Swift-BAT and Fermi-LAT catalogs by interpolating the energy spectra in the hard X-ray and GeV gamma-ray ranges, as well as unmatched sources between the two catalogs. We find that the source contribution to the COMPTEL emission would be at least ∼20%. Combined with the Galactic diffuse emission, which is not well constrained, the COMPTEL emission can be roughly reproduced in some cases.
