Very fast X-ray spectral variability in Cygnus X-1: Origin of the hard and soft-state emission components

Chris J. Skipper, Ian M. McHardy, Thomas J. Maccarone

The way in which the X-ray photon index, Γ, varies as a function of count rate is a strong diagnostic of the emission processes and emission geometry around accreting compact objec…
