Computational Astroparticle Physics

Current Sheet
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.
The video below shows the dynamics of this test by the example of the time evolution of the absolute value of the magnetic field.
