402-0714-00L	Astro-Particle Physics II	W	6 KP	2V + 1U	A. Biland
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

Kurzbeschreibung	The course introduces in detail some of the main observational methods for the detection and characterization of extra-solar planetary systems. It covers the physics of planets (in the solar system and in extra-solar systems) and provides some overview of the current state of this dynamic research field.
Lernziel	The course gives an overview of the current state-of-the-art in exoplanet science and serves as basis for first research projects in the field of exoplanet systems and related topics.
Inhalt	Content of the lecture EXTRASOLAR PLANETS 1. Planets in the astrophysical context 2. Planets in the solar systems 3. Detecting extra-solar planetary systems 4. Properties of planetary systems and planets 5. Planet formation 6. Search for habitable planets and bio-signatures
402-0376-16L	Advanced Statistical Methods in Cosmology and Astrophysics Findet dieses Semester nicht statt. This course is not being offered anymore.	W	6 KP	2V + 1U	Noch nicht bekannt
Kurzbeschreibung	Statistical methods are increasingly important in modern science. In this course we will build an understanding of statistical methods beyond Bayesian inference. These include information content of experiments through relative entropy and ABC methods for difficult problem when the likelihood cannot be calculated. We will also cover topics which are now commonly used in cosmology.

These include information content of experiments through relative entropy and ABC methods for difficult problem when the likelihood cannot be calculated. We will also cover topics, such as power spectrum estimation, which are now commonly used in cosmology.
Voraussetzungen / Besonderes	In this course we will assume good knowledge of statistical inference, so it is recommended that students have taken 'Statistical Methods in Cosmology and Astrophysics' or equivalent.
402-0368-61L	The Sun, Stars and Planets - Properties, Processes and Interactions	W	4 KP	2G	L. Harra, S. P. Quanz
Kurzbeschreibung	The physics of solar flares, coronal mass ejections and the solar wind will be described. A discussion of the similarities and differences to stellar flares and coronal mass ejections will follow. An introduction to the detection and characterization of extrasolar planets, the impact of stellar phenomena on exoplanets and in particular on their potential habitability will be given.
Lernziel	The main goal of the course is to give the students an overview of physical phenomena that lead to impacts on the Earth, planets and exoplanets. The areas described are at the forefront of scientific research internationally, and touch on significant questions such as ‘is there life on other planets’. These topics will be of interest to students studying astrophysics, earth science and planetary sciences.

402-0395-00L	Multimessenger Constraints of Generalizations of Gravity Findet dieses Semester nicht statt.	W	8 KP	3G	L. Heisenberg
Kurzbeschreibung	The LIGO detections of Gravitational Waves have started the field of Gravitational Wave astronomy. This opens an exiting opportunity to test gravity theories in regimes where it has not been tested yet. Together with standard cosmological observations, one can put tight multimessenger constraints on different cosmological models.
Lernziel	These lecture series will be dedicated to combining theory with cosmological observations. First of all, I will discuss the consistent construction of prominent gravity theories, both from a geometrical as well as field theory perspectives. I will introduce more general space-time geometries as well as the building blocks of field theories based on additional degrees of freedom in the gravity sector. Coming from the theory side, I will explain the theoretical constraints and consistency checks that can be applied to fundamental gravity theories. In the observational side, the confrontation of gravity theories with cosmological observations is a crucial ingredient in testing these theories. A natural starting point will be the study of the background evolution. Theory parameters can then be constrained using the distance redshift relation from Supernovae, the distance priors method from CMB and BAO measurements. Given the recent developments in gravitational wave physics, I will discuss the implications of alternative gravity theories in the regime of strong gravity.

Kurzbeschreibung	These lecture series will be dedicated to different advanced topics within the framework of theoretical cosmology and gravity. A detailed introduction into the successful construction of gravitational interactions will be given, together with their cosmological implications.

402-0385-68L	Topics in the Evolution of Galaxies	W	4 KP	1V + 1S	S. Lilly
Kurzbeschreibung	The course examines the formation and evolution of galaxies in the Universe. There will be a general introduction about how we observe the evolution of the Universe, and the theory of dark matter structure formation in the Universe. We will then look at several aspects of the more complex evolution of the "baryonic" component of the Universe, using a combination of lectures and student seminars.
Lernziel	The first goal is to give students an overall understanding of the most important processes observed in the evolving universe. However, another very important goal for this course concerns more the nature of scientific research. By focusing on practical questions at the forefront of our knowledge, the course will also expose students to the challenges that are encountered in carrying out research using "passive" investigations, in this case astronomical observations. These include the challenges of inferring causal relations from data, the meaning of probability when describing classical phenomena, the difficulties of dealing with an evolving population, and the importance of the prevailing paradigm in formulating what are the most interesting scientific questions to be asked. Many of these issues will therefore be of general interest for other emerging areas of science in which large datasets are passively queried.
