| Description | To study the cosmic history of accretion onto black holes (BH), three measurements are crucial: BH mass, bolometric luminosity and radiative efficiency. An ongoing SDSS reverberation mapping (RM) program provides for the first time significantly improved mass estimates for a large sample of QSOs to redshift 3 in a single field of 7 square degrees. With the XMM-Newton observations and existing X-ray data, we propose to measure with high accuracy bolometric luminosity and Eddington ratio for about 170 of these RM QSOs. We will study their disk/corona systems by determining the shape of the optical/UV/X-ray SED and the variability properties of the inner accretion flow, thus constraining the evolution of radiative efficiency, and, possibly, BH spin. |

| 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. |
