X-ray Variability of Cygnus X-1 in Its Soft State
We reported previously that for Cyg X-1 there is a settling period following the transition from hard to soft state (Cui et al. 1996). During the transiton, The low energy spectrum (below ∼ 10 keV) varies significantly from observation to observation while the high energy portion changes little. The source reaches nominal soft-state brightness during the settling period. It can be characterized...
متن کاملUnderstanding the long-term spectral variability of Cygnus X-1 from BATSE and ASM observations
We present a spectral analysis of observations of Cygnus X-1 by the RXTE/ASM (1.5–12 keV) and CGRO/BATSE (20–300 keV), including about 1200 days of simultaneous data. We find a number of correlations between intensities and hardnesses in different energy bands from 1.5 keV to 300 keV. In the hard (low) spectral state, there is a negative correlation between the ASM 1.5–12 keV flux and the hardn...
متن کاملA Self-Consistent Model For The Long-Term Gamma-Ray Spectral Variability of Cygnus X-1
The long-term transitions of the black hole candidate Cygnus X-1 (between the states γ1, γ2, and γ3) include the occasional appearance of a strong ∼ MeV bump (γ1), whose strength appears to be anti-correlated with the continuum flux (<∼ 400 keV) due to the Compton upscattering of cold disk photons by the inner, hot corona. We develop a self-consistent disk picture that accounts naturally for th...
متن کاملUnderstanding the long-term spectral variability of Cygnus X-1 with BATSE and ASM observations
We present a comprehensive analysis of all observations of Cygnus X-1 by the CGRO/BATSE (20–300 keV) and by RXTE/ASM (1.5–12 keV) until 2002 June, including ∼ 1200 days of simultaneous data. We find a number of correlations between fluxes and hardnesses in different energy bands. In the hard (low) spectral state, there is a negative correlation between the ASM 1.5–12 keV flux and the hardness a...
متن کاملOrbital , precessional and flaring variability of Cygnus X - 1
We present the results of a 2.5-year multiwavelength monitoring programme of Cygnus X-1, making use of hard and soft X-ray data, optical spectroscopy, UBVJHK photometry and radio data. In particular we confirm that the 5.6-day orbital period is apparent in all wavebands and note the existence of a wavelength-dependence to the modulation, in the sense that higher energies reach minimum first. We...
