XMM-RM: Quasar Accretion Physics in the Reverberation-Mapping Field

To study the cosmic history of accretion, two reliable measurements are crucial:black hole mass and bolometric luminosity. Our SDSS Reverberation Mapping (RM)program is the first multiobject spectroscopic RM campaign, providingsignificantly improved BH mass estimates for a large sample of quasars toredshift 4 in a single field of 7 square degrees. Now with XMMNewton, we willcharacterize the Xray emission for about 700 of these quasars, enhancingmeasurements of bolometric luminosity and therefore Eddington ratio. From Xraybrightness, powerlaw slopes, and variability characteristics within the sample,we will also test accretion models in correlations that extend across the massrange, from Galactic Xray binaries to quasars. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
