Abstract
We studied how the process of self-modulation of cosmic rays, occurring upon their penetration into dense molecular clouds, affects the total gamma-ray emission of the Galaxy. We estimated how the self-modulation modifies the emission from each individual cloud and integrate the results along the line of sight for a given area in the sky. Our calculations show that the self-modulation reduces the total intensity of gamma-ray emission below 1 GeV by about 10–30%. Even though the magnitude of the effect is not large, it still can substantially affect the background gamma-ray emission at low energies.
