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.

Oort and Extragalactic Astronomy
1980Our understanding of the nature of external galaxies, incomplete as it still is, has depended cast essentially on the understanding of our own Milky Way. And one cannot think of any facet of knowledge about our Galaxy without paying tribute to Jan Oort’s elucidation of its mysteries.
