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

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.
