Title A Modern Quasar SED from XMM-Newton, Spitzer, and SDSS
DOI https://doi.org/10.5270/esa-0cz1gzt
Abstract We request 7 XMM-Newton pointings in the field of the Spitzer First Look Surveyto obtain uniform X-ray data on 100 quasars, including 10 luminous, type Iquasars from the Sloan Digital Sky Survey. With 14.0 ks exposures (98.0 kstotal), we will obtain more than 500 counts on each of the 10 luminous quasarsand at least 40 counts on 100 other quasars in the field of view. We willcharacterize the X-ray, UV, optical, IR, and radio SED of quasars as a functionof various properties, thus permitting better estimates of bolometricluminosity, black hole mass, and accretion rate in addition to providing betterobservational templates for comparison with accretion disk models.

Mission Description The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
