| Description | We propose to obtain XMM-Newton observations for a complete flux-limited sample of 7 of the most mid infra-red luminous quasars (log(L6um) > 47.5) at the main epoch of galaxy and black-hole growth at z 2 3. The main objective is to study the X-ray properties of a new population of hyperluminous, heavily reddened quasars with typical extinctions of 0.5 < E(B V ) < 2.0 and which are therefore not detectable in wide-field optical surveys. These broad-line Type 1 reddened quasars have the expected properties - high Eddington ratios and moderate column-densities - characteristic of the radiative feedback phase. We will constrain the hard X-ray luminosity and neutral hydrogen column density and compare them to optically selected, essentially unobscured 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. |
