Description From a systematic study of the radio properties of luminous red quasars in the SDSS, we have found clear evidence that distinguishes them from the more normal blue quasars, suggesting that they are a special stage in the co-evolution of AGN. To complement an on-going VLT-XSHOOTER program exploring the differences in the accretion disks of red quasars at z=1.5, we propose new XMM-Newton observations of 5 carefully selected targets, which, in combination with an archival dataset of normal quasars, will allow a controlled study of differences in (1) nuclear obscuring columns, (2) intrinsic X-ray to optical spectral slope, and (3) coronal properties. Our study is designed to uncover whether red quasars have systematically different accretion disks from normal 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.
