Long term variability of Cygnus X-1, III. Radio-X-ray correlations
T. Gleissner, J. Wilms, G. G. Pooley +7
Long time scale radio-X-ray correlations in black holes during the hard state have been found in many sources and there seems to emerge a universal underlying relationship which qu…
Different kinds of long-term variability from Cygnus X-1
S. Benlloch, K. Pottschmidt, J. Wilms +3
We present a study of the long-term variability of Cyg X-1 using data from the RXTE/ASM and the RXTE/PCA during the time between the two soft states of 1996 and 2001/2002. This per…
Short-Term Radio-X-ray Correlations of Cygnus X-1
T. Gleissner, J. Wilms, G. G. Pooley +6
We analyze simultaneous radio-X-ray data of Cygnus X-1 from the Ryle telescope (RT) and RXTE over more than 4 a. We show that apparent correlations on short time scales in the ligh…
Long Term Variability of Cyg X-1, II. The rms-Flux Relation
T. Gleissner, J. Wilms, K. Pottschmidt +3
We study the long term evolution of the relationship between the root mean square (rms) variability and flux (the ``rms-flux relation'') for the black hole Cygnus X-1 as monitored…
INTEGRAL-RXTE observations of Cygnus X-1
K. Pottschmidt, J. Wilms, M. Chernyakova +11
We present first results from contemporaneous observations of Cygnus X-1 with INTEGRAL and RXTE, made during INTEGRAL's performance verification phase in 2002 November and December…
Short term X-ray rms variability of Cyg X-1
T. Gleissner, J. Wilms, K. Pottschmidt +3
A linear dependence of the amplitude of broadband noise variability on flux for GBHC and AGN has been recently shown by Uttley & McHardy (2001). We present the long term evolution…
Long Term Variability of Cyg X-1 I. X-ray spectral-temporal correlations in the hard state
K. Pottschmidt, J. Wilms, M. A. Nowak +6
We present the long term evolution of the timing properties of the black hole candidate Cygnus X-1 in the 0.002-128 Hz frequency range as monitored from 1998 to 2001 with the RXTE.…
