Title Witnessing hierarchical structure formation with double & triple galaxy clusters

Author Dr Andrea Morandi
Description Double or triple galaxy clusters are unique candidates to observe the processes related to individual components at an early stage of merging, such as mutual interaction between the components, accretion history of the member clusters and the intercluster medium. We used the metacatalog of X-ray detected clusters of galaxies and the Planck cluster catalogue to select a sample of three double and triple clusters, for which we request XMM time. Through the synergy between XMM and Sunyaev-Zeldovich from Planck, we will recover the thermodynamic properties of the gas and constrain accretion processes in the intercluster region. XMM will therefore play an important role in casting light into these systems and into the physics at the edge between clusters and large-scale structure filaments.

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.
