COMPTEL Observations of the Blazars 3C 454.3 and CTA 102

S. Zhang, W. Collmar, V. Schoenfelder +5

We have analyzed the two blazars of 3C 454.3 and CTA 102 using all available COMPTEL data from 1991 to 1999. In the 10-30 MeV band, emission from the general direction of the sourc…

Gamma-Ray Spectral Variability of Cygnus X-1

M. L. McConnell, K. Bennett, H. Bloemen +11

We have used observations from CGRO to study the variation in the MeV emission of Cygnus X-1 between its low and high X-ray states. These data provide a measurement of the spectral…
