|Title||Probing Accretion and Obscuration in Luminous Red Quasars|
|Author||Prof Eilat Glikman|
|Description||We propose to obtain XMM observations of three highly luminous dust-reddened quasars that appear to be young, transitional objects predicted by merger-driven models of quasar-galaxy co-evolution. These sources have been well-studied in optical through mid-infrared and have Eddington ratios >30%. Their black hole masses are relatively small compared to their host galaxies placing them below the MBH -- Lbulge relation. We propose to exploit the large collecting area of the EPIC cameras to measure NH and constrain the dust-to-gas ratios as well as the photon index as an independent probe of Eddington ratio. We will also measure their X-ray luminosities to compare with the infrared. These observations will complete the multi-wavelength study of this key population of quasars.|

|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.
