|Title||Quest for X-ray emission from the large-scale structure between cluster pairs|

|Description||Our detection of a filament of virgul0.9 keV gas connecting the clusters of galaxies Abell 222 and 223 offered one of the first successful glimpses at a small fraction of the missing baryons in the local Universe. To understand the nature and properties of the Warm Hot Intergalactic Medium (WHIM), it is of utmost importance to extend our search to other promising systems. We propose deep (150 ks each) observations of two pairs of clusters of galaxies in which the filament connecting them is expected to lie approximately along our line-of-sight. This favorable geometry will allow us to detect the WHIM down to an average density of 2-3x10^-5 cm^-3, which is only a factor of two to three larger than the densities that we hope to detect with proposed dedicated future missions.|

|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.
