Thermal/non-thermal model of Cyg X-1 in the soft state
Marek Gierlinski, Andrzej A. Zdziarski, Paolo S. Coppi +3
We analyze X-ray/gamma-ray observations of Cyg X-1 in the soft state. We find the hybrid thermal/non-thermal model fits the data very well. The significant contribution from the no…
Cygnus X-1: X-ray Emission Mechanism and Geometry
Wei Cui, S. N. Zhang, J. H. Swank +3
We summarize recent observations of Cyg X-1 during its 1996 state transition. The results favor an emission geometry with a central optically thin corona surrounded by an optically…
X-ray and gamma-ray spectra of Cyg X-1 in the soft state
Marek Gierlinski, Andrzej A. Zdziarski, Tadayasu Dotani +3
We present X-ray/gamma-ray observations of Cyg X-1 in the soft state during 1996 May-June. We analyze ASCA, RXTE and OSSE data. The spectrum consists of soft X-ray blackbody emissi…
