Vanishing hardness-flux correlation in Cygnus X-1: signs of the disc moving out
M. Axelsson, L. Hjalmarsdotter, L. Borgonovo +1
Aims. We investigate observations of the X-ray binary Cygnus X-1 with unusually high hardness and low flux. In particular, we study the characteristic frequencies seen in the PDS a…

Evolution of the 0.01 - 25 Hz power spectral components in Cygnus X-1
M. Axelsson, L. Borgonovo, S. Larsson
Analyzing the archival data from the Rossi X-ray Timing Explorer (RXTE), we study the power density spectra (PDS) of Cygnus X-1 from 1996 to 2003 in the frequency range of 0.01 - 2…

INTEGRAL & RXTE Power Spectra of Cygnus X-1
K. Pottschmidt, J. Wilms, M. A. Nowak +3
We evaluate 0.03-20 Hz power spectra of the bright black hole binary Cyg X-1 obtained from non-deconvolved INTEGRAL-ISGRI event data. The ISGRI power spectra are compared to contem…
