“…This raises the exciting possibility that the spin energy of the hole is being tapped (Wilms et al 2001). The X-ray continuum emission of MCG-6-30-15 is highly variable (see Vaughan, Fabian & Nandra 2003, Vaughan & Fabian 2004 for recent analyses). If the observed continuum drives the iron fluorescence then the line flux should respond to variations in the incident continuum on timescales comparable to the lightcrossing, or hydrodynamical time of the inner accretion disc (Fabian et al 1989;Stella 1990;Matt & Perola 1992;Reynolds et al 1999).…”

Broad iron lines in AGN and X-ray binaries

Several AGN and black hole X-ray binaries show a clear very broad iron line which is strong evidence that the black holes are rapidly spinning. Detailed analysis of these objects shows that the emission line is not significantly affected by absorption and that the source variability is principally due to variation in amplitude of a power-law. Underlying this is a much less variable, relativistically-smeared, reflection-dominated, component which carries the imprint of strong gravity at a few gravitational radii. The strong gravitational light bending in these regions then explains the power-law variability as due to changes in height of the primary X-ray source above the disc. The reflection component, in particular its variability and the profile of the iron line, enables us to study the innermost regions around an accreting, spinning, black hole.
