Description 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.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
