| Description | We propose to compare X-ray luminosities and temperatures of a sample of confirmed optically-selected zvirgul0.7 clusters to well-determined velocity dispersions and weak-lensing maps. The use of non-X-ray selected clusters enables us to search for large deviations in the X-ray properties relative to other mass tracers. Our extensive VLT, HST, and NTT observational program has provided velocity measurements for between 30 and 60 cluster members per cluster and weak lensing maps augmented with photometric redshift information for six of the most optically luminous clusters at z virgul 0.7 in the Las Campanas Distant Cluster Survey. Here we propose to continue this study by observing three more of these clusters. |

| 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. |
