Recent observations have established redshift 1 as a pivotal epoch in thecreation of galaxy groups. At these redshifts, the group environment changesfrom being invigorating to suffocating for galaxy activity, as the time-scalesfor collapse of structures reach the time scales for galaxy transformation.DEEP2 is the leading spectroscopic galaxy survey at the redshift range of 0.7<z<1.4 , where dramatic changes in the global galaxy population areobserved. We propose XMM observations of the DEEP2 fields, which will signpostgalaxy transformation at these redshifts by identifying X-ray groups anddisentangling the effects of massive halo assembly from those associated withthe stage of structure formation at z=1.

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.
