| Abstract | We propose to continue our successful XMM-Newton program to measure theproperties of the intragroup medium in a sample of galaxy groups at moderateredshifts. Previously, we have observed groups at z=0.2. Here, we propose toextend our study to higher redshifts by observing four X-ray bright groups inthe redshift range z=0.31 to z=0.45. We will combine the new XMM observationswith our existing HST imaging and groundbased spectroscopy to: 1) measure theevolution of metallicity of the intragroup medium from z=0 to nearly z=0.5; 2)determine if the correlations between X-ray properties and morphological contenthold at moderate redshifts; and 3) determine the masses and baryon fractions ofintermediate redshift groups. |

| 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. |
