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

| 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. |
