Kurzbeschreibung | This lecture focuses on the neutral components of the cosmic rays as well as on several aspects of Dark Matter. Main topics will be very-high energy astronomy and neutrino astronomy. | |||||

Lernziel | Students know experimental methods to measure neutrinos as well as high energy and very high energy photons from extraterrestrial sources. They are aware of the historical development and the current state of the field, including major theories. Additionally, they understand experimental evidences about the existence of Dark Matter and selected Dark Matter theories. | |||||

Inhalt | a) short repetition about 'charged cosmic rays' (1st semester) b) High Energy (HE) and Very-High Energy (VHE) Astronomy: - ongoing and near-future detectors for (V)HE gamma-rays - possible production mechanisms for (V)HE gamma-rays - galactic sources: supernova remnants, pulsar-wind nebulae, micro-quasars, etc. - extragalactic sources: active galactic nuclei, gamma-ray bursts, galaxy clusters, etc. - the gamma-ray horizon and it's cosmological relevance c) Neutrino Astronomy: - atmospheric, solar, extrasolar and cosmological neutrinos - actual results and near-future experiments d) Dark Matter: - evidence for existence of non-barionic matter - Dark Matter models (mainly Supersymmetry) - actual and near-future experiments for direct and indirect Dark Matter searches | |||||
