High-resolution X-ray spectroscopy has become a powerful tool for astrophysics since the launch of Chandra and XMM-Newton, ten years ago. The grating spectrometers on both instruments still continue to provide excellent data, while imaging calorimeters are being prepared for future missions like Astro-H and IXO. The synergy with other wavelength bands like the UV has been boosted by the addition of COS to HST. X-ray spectroscopy offers unique diagnostics to study almost any object in the Universe. This book contains review papers on highlights and the state-of-the-art of X-ray spectroscopy for a broad range of objects and on the prospects for future studies.

This book presents a review about the physics of clusters of galaxies beyond the standard thermal view. The book first gives a general introduction to clusters of galaxies. It discusses the properties of the hot, virialised gas in these clusters. But the main focus is upon what is beyond this thermal gas: the surrounding warm-hot intergalactic medium, non-thermal emission components and the chemical enrichment of the clusters and their environments. What is the evolution of the hot gas in clusters and the surrounding cosmic web? How does it reach equilibrium? What is the role of magnetic fields and shocks? Has the WHIM been detetected? Are there non-thermal components in clusters? How does the metallicity evolve? These questions and many others are addressed from three different points of view: observations, theory of the physical processes and numerical simulations.

The book is written as a tutorial review. It is meant as an introduction for professionals and students wishing to work in this field. This means that no attempt is made to give a complete overview of all the work that has been done in this field, but to focus upon what needs to be known to be able to work in this field, and to explain to the reader basic processes, techniques and observations that experts often assume to be common knowledge.
