The Leibniz Institute for Astrophysics Potsdam (AIP) invites applications for Postdoctoral Research Positions (m/f/d) in Computational Galaxy and Cluster Formation who will strengthen our research in the section Cosmology and High-energy Astrophysics. The successful candidates will work on cosmological simulations of the formation and evolution of galaxies and galaxy clusters, with a particular emphasis on the underlying physical processes. Funding for these positions is provided by the ERC advanced grant PICOGAL that pursues a coordinated multi-scale approach, which combines plasma kinetic and global fluid models with the goal to understand the physics of galaxy formation in a cosmological context, including the interstellar, circum- and intergalactic media, galaxies, and galaxy clusters.
