The Soft Gamma-Ray Spectral Variability of Cygnus X-1
M. L. McConnell, A. A. Zdziarski, K. Bennett +11
We have used observations of Cygnus X-1 from the Compton Gamma-Ray Observatory (CGRO) and BeppoSAX to study the variation in the MeV gamma-ray emission between the hard and soft sp…
The Crab pulsar in the 0.75-30 MeV range as seen by CGRO COMPTEL
L. Kuiper, W. Hermsen, G. Cusumano +5
We present the time-averaged characteristics of the Crab pulsar in the 0.75-30 MeV energy window using data from the imaging Compton Telescope COMPTEL aboard the Compton Gamma-Ray…
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…
COMPTEL Observations of the Blazar PKS 1622-297 during a Gamma-Ray High State in 1995
S. Zhang, W. Collmar, V. Schonfelder +6
PKS 1622-297 was detected as a source of gamma-rays by the EGRET experiment at energies above 100 MeV during a gamma-ray outburst June and July 1995. We analyzed the COMPTEL data (…
The Comptel 1.809 Mev Survey
S. Plueschke, R. Diehl, V. Schoenfelder +8
We present the latest update of the 1.809 MeV sky survey obtained with COMPTEL. Based on all observations taken since the launch of CGRO in spring 1991 to early summer this year we…
