Abstract
A list of 25 high-energy (greater than 100 MeV) gamma-ray sources detected by COS B is presented. Only four sources are identified with well-known objects. Of the remaining sources, 20 are at low galactic latitude, and they may represent a new galactic population. Their luminosity is estimated to be in the range of (0.4-5) x 10 to the 36th ergs/sec. It is seen that several hundred such sources may exist in the galaxy. Their nature is not understood.
