Gamma Ray Astronomy
Abstract
Results of gamma-ray astronomy in the energy range above 1 MeV are reviewed. COS-B observations of galactic and extragalactic gamma rays are described. It is concluded that: (1) the cosmic-ray intensity in the galactic disk appears to decrease in the anticenter direction beyond the sun; (2) supernova or pulsar production of a sudden injection of cosmic rays is in conflict with the data unless the energy released is less than several times 10 to the 50th erg or the cosmic rays diffuse rapidly; (3) gamma-ray stars exist; (4) the average energy spectra of gamma rays from the galactic disk are steep; and (5) no localized extragalactic gamma-ray sources have been discovered so far
