According to galaxy formation models, cluster ellipticals formed in high densityregions through hierarchical merging of gas rich sub-components. In localellipticals, the strong correlation observed between black hole and bulge massimplies that galaxy formation is inextricably linked to the build up ofsupermassive black holes. We have found 4 high redshift, X-ray luminous, butheavily absorbed AGN, embedded in strong bursts of star formation revealed inthe submillimetre. Our SCUBA survey shows that the immediate vicinities of theseobjects contain large overdensities of ultraluminous star-forming galaxies whichwill evolve to form clusters. Here we propose to use XMM to observe the earlyevolutionary phases of QSOs in these proto-clusters.

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.
