Title Observations of a representative X-ray luminosity selected galaxy group sample

Author Dr Gabriel Pratt
Description Our current understanding of the X-ray properties of galaxy groups is limited by poor quality data and an inhomogeneous and non-representative coverage of the mass function. We propose to make deep observations of a representative, X-ray luminosity selected sample of 9 galaxy groups drawn from a complete flux-limited catalogue. We will measure the temperature out to R_500 with similar accuracy to that available for high quality observations of nearby clusters (e.g., REXCESS). We will investigate the relative importance of gravitational and non-gravitational processes in setting the observed X-ray properties of group scale haloes, via extensive examination of their structural and scaling properties.

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.
