Welcome to the home page of
Currently, I am leading the research section Cosmology and High-energy
Astrophysics at the Leibniz-Institute for Astrophysics
Potsdam (AIP) and pursue research as a jointly appointed
professor at the University of Potsdam.
Part of the new research section is funded by the European Research
Council through a Consolidator Grant for my project CRAGSMAN, which
seeks to understand The Impact of Cosmic Rays on Galaxy and Cluster
Formation. At the same time, we are continuing our work on understanding the
emergence of large-scale structure in the Local Universe as well as
pursuing exciting research on topics in high-energy astrophysics.
Cosmology. Formation and
evolution of galaxies, galaxy clusters, and large-scale structure in the
Universe; intergalactic medium and Lyman-α forest; supermassive black
holes; cosmological parameter estimation from cluster surveys.
High-Energy Astrophysics. Cosmic
rays, magnetic fields, and radiative processes in galaxies and galaxy clusters;
propagation of ultra-relativistic gamma rays from blazars, pair creation and
plasma instabilities; dark matter theory and indirect detection methods.
Computational Astrophysics. High-performance
computing with the smoothed particle hydrodynamics code GADGET, the adaptive
mesh refinement code FLASH, and the unstructured moving mesh code AREPO.
Radio- and Gamma-Ray Astronomy. Associate member
of the LOFAR Magnetism Key Science Project; external collaboration
member of the Cherenkov telescopes MAGIC, VERITAS, and the Fermi Space
