Abstract. We present the work of an international team at the
International Space Science
Institute (ISSI) in Bern that worked together to review the current
observational and theoretical status of the non-virialised X-ray emission
components in clusters of galaxies. The subject is important for the
study of large-scale hierarchical structure formation and to shed light
on the "missing
baryon" problem. The topics of the team work include thermal emission and
absorption from the warm-hot intergalactic medium, non-thermal X-ray
emission in clusters of galaxies, physical processes and chemical
enrichment of this medium and clusters of galaxies, and the relationship
between all these processes. One of the main goals of the team is to
write and discuss a series of review papers on this subject. These
reviews are intended as introductory text and reference for scientists
wishing to work actively in this field. The team consists of sixteen
experts in observations, theory and numerical simulations.
Key words: Galaxies: clusters: general - intergalactic medium -
large-scale structure of universe - X-rays: galaxy clusters
