|Title||A Survey of Small Galaxy Groups at High redshift|
|Author||Prof Frederik Paerels|
|Description||The combination of the large sensitivity of the XMM cameras and the availability of the results of the CNOC2 Survey for Galaxy Groups now offers the unique opportunity to conduct a highly sensitive survey for the X-ray properties of small Groups at high redshift. With just a single 100ksec exposure, we propose to acquire data on a few dozen Groups addressing a range of issues concerning the physical properties of gas in small Groups. Since a statistical mass estimate from weak lensing exists for the CNOC2 Groups, we will even be able to address the issue of the gas content as a function of total gravitational mass. With a single stroke, XMM can extend our knowledge of the evolution of most of the baryonic matter in the Universe out to high redshift.|

|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.
