Description We have completed a sub-mm survey of powerful high redshift radio galaxies. This revealed strong evolution in the mean sub-mm luminosity with redshift, with a particularly wide variance in sub-mm properties beyond z=3. This range of evolutionary states may reflect the formation epoch of the host spheroids. Here we seek XMM-Newton observations of a carefully chosen sample to investigate whether the most luminous sub-mm sources contain the most heavily absorbed AGN. This will test the popular evolutionary models for the early stages of massive galaxy formation (Silk & Rees 1998, Fabian 1999), which predict a transition from sub-mm source (with a hidden AGN) to a visible quasar. A secondary goal is to search for hot gas associated with early proto-cluster environments.

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.
