cosmic gamma ray background

(gamma-ray radiation seen everywhere)

Cosmic gamma-ray background (CGB) radiation is weak gamma-ray radiation detectable in many directions, from beyond the Milky Way. It is presumed to come from a variety of sources such as blazars, radio galaxies, star forming galaxies, and perhaps supernovae. By definition, it constitutes part of the cosmic background radiation (CBR).
