Enrolement key / Einschreibeschlüssel: AstroPhys21
The lecture provides an introduction into astroparticle physics ranging from neutrino physics and the search for dark matter to the exploration of the high-energy universe using charged cosmic rays, gamma-rays, neutrinos and gravitational waves. The first class of topics aims to understand the sources, abundance and properties of neutrinos and dark matter. The goal of the second class of topics is to understand the high energy, non-thermal universe and the locations and properties of cosmic acceleratoring mechanisms. The lecture provides a mixture of the theoretical background, the experimental findings and the experimental techniques.
Apart from students generally interested in the interdisciplinary field of astroparticle physics, the lecture targets in particular students who want to write their master thesis in the AG Weinheimer or AG Kappes.
1) Brief summary of cosmology
2) Neutrinos from nuclear fusion in the sun, neutrino mass and matter-enhanced neutrino oscillation
3) Evidence, candidates and search for dark matter
4) Primary cosmic radiation: charged cosmic rays, ultra-high energy gamma rays, neutrinos
5) Multimessenger physics and cosmic accelerators
6) Gravitational waves

The lecture provides an introduction into astroparticle physics with focus on the exploration of the high-energy universe using nuclei, gamma-rays, neutrinos and gravitational waves. After an introduction, the acceleration of nuclei and the production of photons and neutrinos as well as their propagation and detection are discussed. This is followed by a chapter on gravitational waves and their detection. Afterwards, the highly topical field of multi-messenger astrophysics is presented by means of two recent examples. The lecture closes with a chapter on the still illusive Dark Matter and the current status of searches for it.
Apart from students generally interested in the interdisciplinary field of astroparticle physics, the lecture targets in particular students who want to write their master thesis in the AG Kappes or AG Weinheimer.
