Long-term X-Ray Spectral Variability in AGN from the Palomar sample observed by Swift
S. D. Connolly, I. M. McHardy, C. J. Skipper +1
We present X-ray spectral variability of 24 local active galactic nuclei (AGN) from the Palomar sample of nearby galaxies, as observed mainly by Swift. From hardness ratio measurem…

Probing the hard and intermediate states of X-ray binaries using short time-scale variability
Chris J. Skipper, Ian M. McHardy
Below an accretion rate of approximately a few per cent of the Eddington accretion rate, X-ray binary systems are not usually found in the soft spectral state. However, at accretio…
