We propose to observe two fields from the CNOC2 redshift survey to study theevolution of galaxies in groups. The proposed observations will allow typicalX-ray groups to be discovered out to z=0.8. The unique aspect of our program isthat we have already identified a large sample of optically-selected groups inthese fields over the same redshift interval. The combination of the X-ray andoptically-selected samples will allow the construction of a sample spanning thefull range of dynamical states of groups.

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.
