Title The Evolution of Galaxies in Groups

Description We propose to observe two fields from the CNOC2 redshift survey to study the evolution of galaxies in groups. The proposed observations will allow typical X-ray groups to be discovered out to z=0.8. The unique aspect of our program is that we have already identified a large sample of optically-selected groups in these fields over the same redshift interval. The combination of the X-ray and optically-selected samples will allow the construction of a sample spanning the full range of dynamical states of groups.

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.
