| Description | From a systematic study of the radio properties of luminous red quasars, we have found clear evidence that distinguishes them from normal quasars, suggesting that they are a special stage in AGN co-evolution with galaxies. To complement an on-going VLT/XSHOOTER program to explore 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 (1) differences in nuclear obscuring columns, (2) intrinsic X-ray--optical spectral slope, and (3) coronal properties. With this, we aim to uncover whether red quasars have special accretion engines and mass outflow rates. |

| 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. |
