In theoretical cosmology and astroparticle physics, we deal with questions about the composition of the universe, the origin of matter, and the fundamental principles responsible for cosmological and astrophysical phenomena. In the interplay between elementary particle physics and the theory of general relativity we describe the evolution of the universe from the first moments after the Big Bang until today. In our research, we deal among others with the puzzle of dark matter, the properties of neutrinos, the matter-antimatter asymmetry and gravitational waves.

The central lecture in the field of theoretical cosmology and astroparticle physics is (Introduction to) Theoretical Cosmology, in which the Big Bang model is introduced. You will study various aspects of modern cosmology, from the expansion of the universe, dark matter and dark energy, to the formation of the first chemical elements shortly after the Big Bang, the cosmic microwave background radiation, and cosmic structure formation. In the lecture Introduction to General Relativity, we discuss the Einstein equations as the basis of gravity, as well as black holes, cosmology and gravitational waves as important applications.

In addition, there is a wide range of special lectures in which various aspects of cosmology or astroparticle physics are dealt with in greater depth.

Most lectures are accompanied by exercises in which the mathematical methods are applied to numerous practical examples. The exercises offer a first insight into the working methods of theoretical astroparticle physics and are therefore an ideal preparation for a Master's thesis.

In the advanced seminar you have the opportunity to familiarize yourself with a current research topic in the context of a presentation.
