Probing the inner accretion region with a 2 Ms observation on a nearby and highly variable AGN
Abstract
The fast timing properties of accreting black hole light curves allow us to probe the direct vicinity of black holes, the region most affected by strong gravity. We present an extensive X-ray variability analysis from a new 1.5 mega-second XMM-Newton VLP observation (plus 500 ks archival = 2Ms) of the highly variable Seyfert 1 galaxy, IRAS 13224-3809. This is the longest observation taken to date on a nearby variable AGN. This long observation has revealed complex underlying variability processes, displaying the first non-linear rms-flux relation in any accreting source. We will show modelling of the coronal and reverberation delays using GR ray tracing models. This allows us to build up the most detailed picture to date of the inner X-ray emitting regions of AGN. We discuss the implication of these results for accreting sources across the mass range.
