| Abstract | We have completed a sub-mm survey of powerful high redshift radio galaxies. Thisrevealed strong evolution in the mean sub-mm luminosity with redshift, with aparticularly wide variance in sub-mm properties beyond z=3. This range ofevolutionary states may reflect the formation epoch of the host spheroids. Herewe seek XMM-Newton observations of a carefully chosen sample to investigatewhether the most luminous sub-mm sources contain the most heavily absorbed AGN.This will test the popular evolutionary models for the early stages of massivegalaxy formation (Silk & Rees 1998, Fabian 1999), which predict a transitionfrom sub-mm source (with a hidden AGN) to a visible quasar. A secondary goal isto search for hot gas associated with early proto-cluster environments. |

| 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. |
