Abstract | Double or triple galaxy clusters are unique candidates to observe the processesrelated to individual components at an early stage of merging, such as mutualinteraction between the components, accretion history of the member clusters andthe intercluster medium. We used the metacatalog of X-ray detected clusters ofgalaxies and the Planck cluster catalogue to select a sample of three double andtriple clusters, for which we request XMM time. Through the synergy between XMMand Sunyaev-Zeldovich from Planck, we will recover the thermodynamic propertiesof the gas and constrain accretion processes in the intercluster region. XMMwill therefore play an important role in casting light into these systems andinto the physics at the edge between clusters and large-scale structure filaments. |

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. |
