|Title||Tracing a filament in the outskirts of the Shapley Supercluster|

|Description||We propose two XMM-Newton snapshot observations to detect all the point sources in the region between the double galaxy cluster A3528 and the complex A3530- A3532, in which we have discovered hints of a filamentary emission. These snapshots will complement our Suzaku observations. We aim to detect the hottest and densest phase of the Warm Hot Intergalactic Medium in the vicinity of clusters by its thermal soft X-ray emission. For this purpose, we will use the XMM-Newton observations to correct precisely for the point sources, resulting in an improvement of the temperature measurement uncertainty by a factor of three. In addition to a full understanding of the typical baryon fraction, we will study the possible gas clumping in the cluster outskirts.|

|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.
