In the work group Accretion, Active Galaxies, Astrobiology, under administration of Prof. Dr. W. J. Duschl, both high-energy processes which drive the growth of supermassive black holes, as well as the conditions for habitability of exoplanets are investigated.

The overlap lies in the numerical methods, a large portion of which falls into the field of fluid dynamics. The same equations describe the atmospheres of planets and accretions disks, respectively. In order to make these CPU-intensive simulations possible, supercomputer are used.
