| Abstract | There is a place in the sky where the projected density of galaxy clusters isfactor 6 above average - a chain of superclusters spanning z=0.08-0.2, or 500Mpc along the line of sight. Such fortuitous natural stacking of matterconcentrations improves our chances to detect signatures of the intergalacticmedium (WHIM). Intriguingly, our preliminary analysis of the public Planck datahints at faint SZ signal from regions beyond known individual clusters. Wepropose a shallow XMM survey of this scarcely observed area in order to detectall clusters down to 1e43 erg/s, to be followed up with deeper observations foraccurate SZ modeling. We will then model away the cluster SZ contribution andsee if anything is left that can be attributed to WHIM in this giant filament. |

| 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. |
