Extragalactic ?-ray astronomy

Space Science Reviews, 1983
Extragalactic γ-ray astronomy is in its infancy. In this paper a review is presented of the γ-ray emission of the few individual objects observed to date and some conclusions are drawn as to their possible general characteristics. A number of scenarios suitable for the generation of γ-rays are presented in the light of these recent measurements.
