Where in the universe are heavy elements synthesized? How are these elements produced?
We work along two lines to understand the origin of heavy elements: astrophysics simulations of supernova explosions and compact binary mergers that probe nuclear matter at the extremes combined with nucleosynthesis calculations, which involve the most neutron-rich nuclei. The nuclear physics input and the evolution of the astrophysical environment are the most important ingredients of the nucleosynthesis calculations. The impact of the nuclear physics input is studied in our group in close collaboration with theory and experimental groups at GSI, TU Darmstadt, and other international institutions.
