Preliminary INTEGRAL Analysis of GRB040106
L. Moran, L. Hanlon, A. von Kienlin +9
On January 6th 2004, the IBAS burst alert system triggered the 8th gamma-ray burst (GRB) to be detected by the INTEGRAL satellite. The position was determined and publicly distribu…
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…
Multifrequency Observations of the Virgo Blazars 3C 273 and 3C 279 in CGRO Cycle 8
W. Collmar, S. Benlloch, J. E. Grove +15
We report first observational results of multifrequency campaigns on the prominent Virgo blazars 3C 273 and 3C 279 which were carried out in January and February 1999. Both blazars…
The Spectral Variability of Cygnus X-1 at MeV Energies
M. L. McConnell, K. Bennett, H. Bloemen +8
In previous work, we have used data from the first three years of the CGRO mission to assemble a broad-band -ray spectrum of the galactic black hole candidate Cygnus X-1. Contem…
COMPTEL Time-Averaged All-Sky Point Source Analysis
W. Collmar, V. Schoenfelder, A. W. Strong +5
We use all COMPTEL data from the beginning of the CGRO mission (April '91) up to the end of CGRO Cycle 6 (November '97) to carry out all-sky point source analyses in the four stand…
