| Description | We request 7 XMM-Newton pointings in the field of the Spitzer First Look Survey to obtain uniform X-ray data on 100 quasars, including 10 luminous, type I quasars from the Sloan Digital Sky Survey. With 14.0 ks exposures (98.0 ks total), we will obtain more than 500 counts on each of the 10 luminous quasars and at least 40 counts on 100 other quasars in the field of view. We will characterize the X-ray, UV, optical, IR, and radio SED of quasars as a function of various properties, thus permitting better estimates of bolometric luminosity, black hole mass, and accretion rate in addition to providing better observational templates for comparison with accretion disk models. |

| 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. |
