ABSTRACT
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 (z~0.03). 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.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
