A Multi-frequency campaign on the gamma-ray loud blazar W Comae
M. Maisack, K. Mannheim, R. D. Geckeler +10
We report preliminary results of a multi-frequency campaign on the TeV candidate blazar W Comae (z=0.102). Flux limits by Whipple and HEGRA show that the TeV flux must be considera…
Self-Consistent Thermal Accretion Disk Corona Models for Compact Objects: II. Application to Cygnus X-1
James B. Dove, Jorn Wilms, Michael Maisack +1
We apply our self-consistent accretion disk corona (ADC) model, with two different geometries, to the broad-band X-ray spectrum of the black hole candidate Cygnus X-1. As shown in…
Pulse Phase Spectroscopy of A 0535+26 during its 1994 giant outburst observed with OSSE
M. Maisack, J. E. Grove, E. Kendziorra +3
We present pulse phase spectroscopy of A 0535+26 in the energy range 35-200 keV from OSSE observations of its giant outburst in 1994. We discuss the phase dependence of the continu…
Constraints on the 3-30 MeV emission of Seyfert galaxies
M. Maisack, K. Mannheim, W. Collmar
Seyfert galaxies have not been detected by COMPTEL on the Compton Gamma Ray Observatory (CGRO) in the energy range 0.75-3 MeV, placing upper limits on their emission which are more…
OSSE Observations of the Radio Quiet Quasar PG 1416-129
R. Staubert, M. Maisack
We report the detection of the bright radio quiet quasar PG 1416-129 by the OSSE instrument on the Compton Gamma Ray Observatory (CGRO). This object had the hardest spectral index…
