Research

Astroparticle physics combines insights from high-energy physics, cosmology, and astrophysics. We use methods and observations from each of these fields and leverage the interplay of physics at the very smallest and very largest length scales to understand our Universe and search for new physics.

Some of the questions that arise in this context are:

• What is the nature of dark matter?
• How was it produced in the early Universe and how can we detect it?
• Why is there more matter than antimatter?
• How are neutrino masses realized in nature? 
• Which role did they play in the early Universe and can we use them to test new physics?

The Theoretical Astroparticle Physics Group at Freiburg University  works mostly on dark matter, neutrino physics and, collider phenomenology of physics beyond the Standard Model. Our focus is on the phenomenological consequences of models for new physics and the interpretation of experimental data.
