Reading

The lectures will mostly be based on the following books:

  • J.G. Kirk, D.B. Melrose, E.R. Priest, Plasma Astrophysics
  • M. Longair. High-Energy Astrophysics. Cambridge

  • Steven J. Schwartz. Astrophysical Plasmas Online Book

Overview

Most baryonic matter in the Universe is in the form of plasma. Plasma physics is essential to understand astronomical sources, as e.g. stars, active galaxies, pulsars, gamma-ray burst, galaxy clusters or the Cosmic Microwave Background. This lecture will give in introduction to the theory of Magnetohydrodynamics used to describe magnetized plasmas. It will focus on high-energy phenomena occurring within these plasmas, such as particle acceleration and the related emission of high-energy radiation.

The covered topics will include:

  • Observational overview of the high-energy universe
  • Introduction to Magnetohydrodynamics
  • Radiation processes in cosmic plasmas
  • Particle acceleration in cosmic plasmas (shock acceleration, magnetic reconnection)
  • Theoretical introduction to high-energy sources as pulsars, active galaxies, galaxy clusters, super nova remnants and our Sun
