论文摘要
内部银河发射的起源，由comptel以$ \ sim 10^{ - 2}〜{\ rm mev〜cm}^{ - 2}^{ - 2}〜{\ rm s}^{\ rm s}^{ - 1}^{ - 1}〜{\ rm sr}^{\ rm sr}^{-1-1} $从1-30 mev的范围中置于1-30 mev rest的范围发现。在本文中，我们详细阐述了COMPTEL未解决的单个MEV伽马射线源模型。这是针对Swift-Bat和Fermi-Lat目录之间交叉匹配的来源通过在硬X射线和GEV伽马射线范围以及两个目录之间无与伦比的来源中插值的。我们发现，对COMPTEL排放的源贡献至少为约20％。结合银河分散发射的结合，在某些情况下可以大致复制COMPTEL发射。
The origin of the inner Galactic emission, measured by COMPTEL with a flux of $\sim 10^{-2} ~{\rm MeV~ cm}^{-2}~ {\rm s}^{-1}~ {\rm sr}^{-1}$ 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.
