Active projects
Neutrinos in the Early Universe
Marco Drewes, Yuanzhen Li

We study the production and interactions of neutrinos in the primordial plasma from first principles of quantum field theory. This includes Standard Model computations such as QED corrections to Neff as well as constraints on new neutrinos species from cosmology and astrophysics.
Non-thermal Dark Matter
Mubarak Abdallah, Marco Drewes, Yuanzhen Li, Valentin Weber

We study the production of Dark Matter from non-thermal initial states in the early universe, e.g., in freeze-in scenarios. A focus of the project lies in the computation of thermal corrections.
