The effect of radiation pressure on dusty absorbing gas around AGN
A. C. Fabian, R. V. Vasudevan, P. Gandhi
Many Active Galactic Nuclei (AGN) are surrounded by gas which absorbs the radiation produced by accretion onto the central black hole and obscures the nucleus from direct view. The…
Broad iron K-alpha emission lines as a diagnostic of black hole spin
Christopher S. Reynolds, Andrew C. Fabian
We address the ability of broad iron emission lines from black hole accretion disks to diagnose the spin of the black hole. Using a high-resolution 3-dimensional MHD simulation of…
XMM-Newton and Broad Iron Lines
A. C. Fabian
Iron line emission is common in the X-ray spectra of accreting black holes. When the line emission is broad or variable then it is likely to originate from close to the black hole.…
Cool X-ray emitting gas in the core of the Centaurus cluster of galaxies
J. S. Sanders, A. C. Fabian, S. W. Allen +3
We use a deep XMM-Newton Reflection Grating Spectrometer observation to examine the X-ray emission from the core of the Centaurus cluster of galaxies. We clearly detect Fe-XVII emi…
Implications of very rapid TeV variability in blazars
Mitchell C. Begelman, Andrew C. Fabian, Martin J. Rees
We discuss the implications of rapid (few-minute) variability in the TeV flux of blazars, which has been observed recently with the HESS and MAGIC telescopes. The variability times…
X-ray active galactic nuclei in the core of the Perseus cluster
S. Santra, J. S. Sanders, A. C. Fabian
We present a study of the X-ray emission from the nuclei of galaxies observed in the core of the Perseus cluster in a deep exposure with Chandra. Point sources are found coincident…
