We propose 880ks XMM-Newton observations of the most massive, bright,high-redshift galaxy clusters in the Universe detected in the first All-SkySurvey. The XMM-Newton data will enable detailed studies of the density andtemperature structure of the intracluster medium (ICM) in these clusters ofgalaxies. Precise ICM mass measurements and temperature information will enhancethe pioneering eROSITA studies of the evolution of baryons in their deeppotential wells by constraining the properties of this crucial massive clusterpopulation. Furthermore, by combining the eROSITA data with the proposedXMM-Newton follow-up observations, we will constrain the detailed structureformation process as a function of mass, redshift, and environment as well as understanding the (an-)isotropy of the Universe.

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.
