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

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.
