Gamma-Ray Sources: A Puzzle, or a Piece of the Puzzle?
Abstract
The gamma-ray satellite COS-B has, at this time, detected twenty high-energy (greater than 50 MeV) gamma-ray sources. Two sources are pulsars (PSR 0531+21 and PSR 0833-45) and one source has been identified with the quasar 3C 273. The remaining sources are as-yet unidentified galactic objects. Compact objects in which particle acceleration and gamma-ray emission occur in a well-ordered geometry (like pulsars) seem to be attractive candidates. The analogy with the well-defined geometry of quasars and radio galaxies suggests that their nuclei contain a powerful gamma-ray source.
