Observation of gamma rays with a 4.8 hour periodicity from Cyg X-3
Description
Energetic (E>35 MeV) gamma rays were observed from Cyg X-3 with the SAS-2 gamma ray telescope. They are modulated at the 4.8 -h period observed in the x-ray and infrared regions, and within the statistical error are in phase with this emission. The flux above 100 MeV has an average value of (4.4 +- 1.1) x 10-6. If the distance to Cyg X-3 is 10 kpc s, this flux implies a luminosity of more than 1037 ergs/s if the radiation is isotropic and about 1036 ergs/s if the radiation is restricted to a cone of one steradian, as it might be in a pulsar
