SED (in particular, X-‐rays) well described by RIAF (Radiatively Inneficient Accretion Flow): inner RIAF drives the line emission in the disk; Next step: reverberation mapping: observations in X-‐rays, UV and optical continuum simultaneous to spectroscopy to cross-‐correlate with variations in the profile Prediction: ~7 days delay (mean radius of the ring is about 7 light-‐days) -‐> independent measure of the mass of the SMBH 5/16/12 Thaisa Storchi Bergmann, Science with LSST 14
Reverberation in a “double-‐peaker”: Shapovalova et al. 2001: § Flux variation in Hβ lag the one in the continuum (5100A) -‐> delay is a measure of the mean radius of the emitting ring -‐> measure of the black hole mass § Inverse correlation between flux and width of the profile, as in NGC1097 5/16/12 Thaisa Storchi Bergmann, Science with LSST 15
