| Abstract | Structure formation is still ongoing via merging and accretion of gas andgalaxies onto massive clusters. These processes can be best observed in thecluster outskirts. More specifically, filaments between clusters are a uniquelaboratory to study structure formation since they represent a transition zonebetween the virialized, self-gravitating Intercluster medium, and the cooler,less dense warm-hot intergalactic medium filling the cosmic web. Focusing on theideal-configuration of an SZ-selected cluster pair, the present proposal aims atperforming an unprecedented joint X-ray-tSZ analysis of the transition fromfilaments to clusters. With this, we will address key questions such as: whatis 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 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. |
