| Abstract | We propose XMM-Newton observations of the 8 most massive clusterscurrently identified from the Deep Lens Survey (DLS). The DLSmass-selected cluster sample makes it possible for the first time tostudy clusters in a baryon-independent way. XMM-Newton observationswill meet multiple high-impact scientific goals, specifically, testingthe fair sample hypothesis, calibrating the relationships betweencluster mass and X-ray luminosity and temperature, and studying theevolution of these relationships with look-back time. |

| 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. |
