| Abstract | We propose to obtain EPIC-PN imaging of 5 X-ray selected galaxy clusters at z >0.7 in the ROSAT Distant Cluster Survey (RDCS). Using these data, we willmeasure the X-ray morphology of the clusters and their temperatures to ~20%.These observations would allow us to complete the measurement of X-raytemperatures for all 14 clusters at z>0.7 found in the RDCS. We will use thenew XMM data to achieve the following science goals with our full sample at z >0.7: 1) probe the high-z X-ray cluster luminosity-temperature (L-T) relation atL_x ~ 0.5e44-8e44 erg/s, 2) construct the cluster T_x function at high-z, and3) to investigate the dependence of the cluster mass-T_x relation with redshiftusing weak lensing maps. |

| 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. |
