Description Structure formation is still ongoing via merging and accretion of gas and galaxies onto massive clusters. These processes can be best observed in the cluster outskirts. More specifically, filaments between clusters are a unique laboratory to study structure formation since they represent a transition zone between the virialized, self-gravitating Intercluster medium, and the cooler, less dense warm-hot intergalactic medium filling the cosmic web. Focusing on the ideal-configuration of an SZ-selected cluster pair, the present proposal aims at performing an unprecedented joint X-ray-tSZ analysis of the transition from filaments to clusters. With this, we will address key questions such as: what is the physical state of the hot gas in filaments and how did it accret and heat to form the ICM.

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.
