Book
This volume presents the lecture notes of the 24th Advanced Course of the Swiss Society for Astrophysics and Astronomy in March 1994 at Les Diablerets. In three lectures on magnetohydrodynamics, on kinetic plasma physics and on particle acceleration leading experts describe the physical basis of their subjects and extend the discussion to several a...
Book
The Swiss Society for Astrophysics and Astronomy organizes each year in the late winter or early spring an advanced course. The format of the school is always iden­ tical: three leading lecturers are invited to cover the subject in nine or ten lectures each and to deliver a written version of their lecture notes. Lectures are held in the morning an...

... Broad line region (BLR) and narrow line region (NLR)). Type-1 AGNs are associated with emission from BLR that produces lines with FWHMs ranging from 1000-10000 km s −1 (Peterson 1997) while type-2 AGNs exhibit FWHMs ≤ 1000 km s −1 arising from the orbiting clouds forming the NLR (Blandford et al. 1990). These orbiting clouds in random direction are photoionized by the high energy radiation exhibiting from the accretion disk close to the SMBH. ...
... Particle acceleration processes provide an alternative way to accelerate particles in the absence of a global electric field. The existing literature (Blandford 1994;Kirk et al. 1994;Melrose 1996) suggests three main approaches to accelerate charged particles in an astrophysical plasma environment: shock acceleration (DSA), coherent electric field acceleration, and stochastic acceleration (STA). ...
