|Title||A SHALLOW SURVEY OF THE AQUARUIS ECLUSTER FIELD|
|Author||Dr Maxim Markevitch|
|Description||There is a place in the sky where the projected density of galaxy clusters is factor 6 above average - a chain of superclusters spanning z=0.08-0.2, or 500 Mpc along the line of sight. Such fortuitous natural "stacking" of matter concentrations improves our chances to detect signatures of the intergalactic medium (WHIM). Intriguingly, our preliminary analysis of the public Planck data hints at faint SZ signal from regions beyond known individual clusters. We propose a shallow XMM survey of this scarcely observed area in order to detect all clusters down to 1e43 erg-s, to be followed up with deeper observations for accurate SZ modeling. We will then model away the cluster SZ contribution and see if anything is left that can be attributed to WHIM in this giant filament.|

|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.
