Resistive and collisionless magnetic reconnection -- Rotating MHD winds -- Particle acceleration -- Turbulence, statistics and structures: an introduction -- Radio astronomical diagnostics -- Spectroscopic diagnostics of astrophysical plasmas -- Hot plasmas in space: X-ray diagnostic instrumentation.

The book contains the notes of the lectures presented by outstanding experts at the 7th EADN School on plasma astrophysics. It is an up-to-date review of a number of basic topics in the physics of cosmic plasmas. The subject is treated both from a theoretical point of view and from that of the observational and diagnostic tools that provide us with the physically relevant data. The reader will have at hands a comprehensive and rather complete presentation of the subject, thanks also to the parallel development of the theoretical and experimental aspects. The book addresses graduate students and researchers in different areas who want to have a rapid and up-to-date introduction to this subject.
