Computational Astroparticle Physics

In the computational astroparticle phyics group we investigate astrophysical systems with relevance for the transport of cosmic rays by using dedicated numerical methods. In this context there are two numerical codes currently developed in our group: the Picard code for the investigation of cosmic-ray transport and the Cronos code for simulation of (magneto-) hydrodynamical fluids. As an example the image of the right-hand side shows a solution of the so-called current-sheet test as computed with the Cronos code.

For more details regarding the numerical codes see here for the Picard code or here for the Cronos code, respectively.

These codes are applied to investigate different astrophysical systems with a focus on cosmic-ray transport and ensuing gamma-ray emission. Currently, we investigate cosmic-ray transport on the scale of the Milky Way (see here for further details) and in colliding-wind binary systems.
