RXTE Observations of Cygnus X-1: Broad-Band Spectra and High-Resolution Timing
K. Pottschmidt, J. Wilms, M. A. Nowak +3
We present results from a 20 ksec RXTE observation of the black hole candidate Cyg X-1. We apply self-consistent accretion disk corona models to these hard state data and show that…

Analyzing short-term X-ray variability of Cygnus X-1 with Linear State Space Models
K. Pottschmidt, M. Koenig, J. Wilms +1
Cyg X-1 exhibits irregular X-ray variability on all measured timescales. The usually applied shot noise models describe the typical short-term behavior of this source by superposit…
