The effect of environment is an essential, but poorly understood ingredient ingalaxy formation. We propose to measure the gas and dark matter in the clumpsand filaments around two massive distant galaxy clusters. By combining highquality XMM data with our existing wide-field optical-NIR imaging andspectroscopy we will perform a census of the baryons in the large scalestructure around these clusters and measure the effects of environment on thefundamental physical properties of the member galaxies.

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.
