Abstract | Our current understanding of the X-ray properties of galaxy groups is limited bypoor quality data and an inhomogeneous and non-representative coverage of themass function. We propose to make sufficiently deep observations of arepresentative X-ray luminosity selected sample of 10 galaxy groups to detectthe emission out to virgul R_500 with similar accuracy to that available forobservations of nearby clusters. With these data we will investigate therelative importance of gravitational and non-gravitational processes in settingthe observed X-ray properties of group scale haloes, via extensive examinationof their structural and scaling properties. |

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. |
