Abstract (from CDS):

We report on the results of the first XMM-Newton systematic ``excess variance'' study of all the radio quiet, X-ray un-obscured AGN. The entire sample consist of 161 sources observed by XMM-Newton for more than 10ks in pointed observations, which is the largest sample used so far to study AGN X-ray variability on time scales less than a day. Recently it has been suggested that the same engine might be at work in the core of every black hole (BH) accreting object. In this hypothesis, the same variability should be observed in all AGN, once rescaled by the MBH (MBH) and accretion rate ({dot}(m)). We systematically compute the excess variance for all AGN, on different time-scales (10, 20, 40 and 80ks) and in different energy bands (0.3-0.7, 0.7-2 and 2-10keV). We observe a highly significant and tight (∼0.7dex) correlation between σ2rms and MBH. The subsample of reverberation mapped AGN shows an even smaller scatter (only a factor of 2-3) comparable to the one induced by the MBH uncertainties. This implies that X-ray variability can be used as an accurate tool to measure MBH and this method is more accurate than the ones based on single epoch optical spectra. This allows us to measure MBH for 65 AGN and estimate lower limits for the remaining 96 AGN. On the other hand, the σ2rms vs. accretion rate dependence is weaker than expected based on the PSD break frequency scaling. This strongly suggests that both the PSD high frequency break and the normalisation depend on accretion rate in such a way that they almost completely counterbalance each other (PSDamp ∝{dot}(m)–0.8). A highly significant correlation between σ2rms and 2-10keV spectral index is observed. The highly significant correlations between σ2rms and both the LBol and the FWHMHβ are consistent with being just by-products of the σ2rms vs. MBH relation. The soft and medium σ2rms is very well correlated with the hard σ2rms, with no deviations from a linear one to one correlation. This suggests that the additional soft components (i.e. soft excess, warm absorber) add a minor contribution to the total variability. Once the variability is rescaled for MBH and {dot}(m), no significant difference between narrow-line and broad-line Seyfert 1 is observed. The results are in agreement with a picture where, to first approximation, all local AGN have the same variability properties once rescaled for MBH and {dot}(m).
