Abstract The existence of a warm-hot intergalactic medium (WHIM) can solve two puzzles:Why galaxy clusters do not follow classical scaling relations and Where are thelocal baryons observed at high z. Our XMM observations of the outskirts of theComa cluster detect the WHIM viewed along a filament. Its X-ray temperature is0.2 keV and OVII and OVIII emission lines are observed at CCD resolution.Remarkably, a bright AGN is also projected on the WHIM, so grating observationscan detect OVII and OVIII absorption lines. The redshift and width of the lineswill determine where the gas is and its size along the line of sight. Thecombination of emission and absorption lines from the same species providesadditional diagnostics of the properties of the WHIM.

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.
