The contribution of discrete sources to the gamma -ray emission of the Galaxy.
Abstract
The contribution of discrete sources to the galactic gamma-ray emission is discussed on the basis of the recent observations of gamma-ray sources by the COS B satellite. It is shown that if the sources are uniformly distributed throughout the Galaxy, they can account for at least 40 percent of the galactic gamma-ray luminosity. The whole galactic luminosity can be due to discrete sources if their density within 5 kpc of the galactic center is substantially higher than in the outer regions of the Galaxy.
