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 6 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 over-densities of ultraluminous star-forming galaxieswhich will evolve to form clusters. Here we propose to use XMM-Newton to observethe early evolutionary 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.
