Blazars and the emerging AGN/black hole X-ray binary paradigm
P. Uttley
We briefly review the emerging paradigm which links the radio-quiet and radio-loud classes of AGN to the different accretion states observed in stellar mass black hole X-ray binary…
X-ray variability of NGC 3227 and NGC 5506 and the nature of AGN `states'
P. Uttley, I. M. McHardy
We use X-ray monitoring data obtained over a broad range of time-scales to measure the broadband power spectral density functions (PSDs) of two Seyfert galaxies, the broad line Sey…
The relation between optical and X-ray variability in Seyfert galaxies
P. Uttley
Studying simultaneous optical and X-ray light curves of radio-quiet AGN can help to probe the relationship between very different physical components - the cool, optically thick di…
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…
