| Abstract | We propose to use the combined observational power of XMM-Newton and VLT tostudy important aspects of cosmic evolution with massive clusters and groups ofgalaxies. Using a small sample of well defined, X-ray selected very massiveclusters and groups of galaxies from the REFLEX Survey as cosmic laboratories weaim for a simultaneous study of the cluster masses and mass-to-light ratios, thedynamical ages, the mass fractions of various matter components, the galaxypopulations, the heavy element abundances, the supernova rates, the entropystructure of the intracluster medium, and the large scale structure environmentsof these systems. Most importantly we will study the interconnections andcorrelations of these phenomena. |

| 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. |
