This is a continuation of an approved AO-11 program. Although most of theWarm-Hot Intergalactic Medium (WHIM) has yet to be found, an extremely promisingcandidate for the typical WHIM gas is our detection of an OVII K-alphaabsorption line located in the Sculptor Wall superstructure of galaxies(zvirgul0.03). We propose a deep 390ks RGS observation of the Sculptor Wall absorberthat, combining with the planned AO-11 program, will detect the OVII K-beta lineat the 4-sigma level and the OVII K-alpha line at >5-sigma level. The existenceof the K-beta line provide crucial objective evidence for its WHIM nature, anddistinguish the absorber from the type of gas found in a galaxy like the MilkyWay, and from the high density tail of the WHIM detected in emission.

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.
