X-ray variability patterns and radio/X-ray correlations in Cyg X-1
X-ray variability patterns and radio/X-ray correlations in Cyg X-1
We have studied the X-ray variability patterns and correlations of the radio and X-ray fluxes in all spectral states of Cyg X-1 using X-ray data from RXTE/ASM, CGRO/BATSE, and Swift/BAT. In the hard state, the dominant spectral variability is a changing of normalisation with fixed spectral shape, while in the …
