    High Energy Astrophysics - Selected Topics

    Jointly taught by Christoph Pfrommer and Huirong Yan

    The course intends to give a broad overview and covers recent developments in cosmic ray physics and high-energy radiative processes. We will cover some interesting applications ranging from small scales in solar physics, over the inter-stellar medium in galaxies to the largest scales with clusters of galaxies. Marks will be based on four weekly assignments. Topics include:

    • cosmic ray transport
    • diffusive shock acceleration (Fermi I)
    • stochastic acceleration (Fermi II)
    • magneto-hydrodynamical turbulence in cosmic ray physics
    • radiative and non-radiative processes in clusters and galaxies
