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.
