The Leibniz-Institute for Astrophysics Potsdam (AIP) invites applications for a doctoral student position in Computational Galaxy Formation for a project on cosmic ray and radiation feedback. The project aims at studying a diverse set of problems ranging from the plasma physics of cosmic-ray transport, to exploring the impact of cosmic rays and magnetic fields on the formation and evolution of galaxies, to verifying the resulting non-thermal signatures. The PhD project will develop code and conduct high-resolution magneto-hydrodynamical simulations of galaxy formation with a multi-phase interstellar medium. Funding for this position is provided by the European Research Council (ERC) through the PICOGGAL project Mind the Gap: from Plasma Kinetics to Cosmological Galaxy Formation.
