Scientific paper

We propose for XMM-Newton observations of quasars at redshift greater then 2 for which black holes masses have been well measured through infrared spectroscopy. At lower redshift, black hole mass and accretion rate relative to Eddington limit are found to correlate with X-ray spectral slope and X-ray luminosity. With well measured, H-beta based black hole masses we will be able to test whether the same correlations hold for luminous quasars at high redshift with high mass black holes of billion to ten billion solar masses. This study will have direct implications for our understanding of the accretion physics, outflow dynamics, quasar evolution, and black hole growth.
