Computational astrophysics is a central part of modern, astronomical research. The conditions of astrophysical environments (stars, galaxies) are impossible to recreate in the laboratory, but are often too complex to describe with simple mathematical models. By constructing complex computer models of the essential physical processes, we can better interpret observational results, and improve our understanding of the inner workings of astrophysical environments. In this sense computational astrophysics can be said to be the experimental branch of astronomical research. The ever increasing power of computers allow us to perform ever more detailed simulations of complex astronomical phenomena.

At the Department of Astronomy, development of computational tools spans over all research areas, from solar physics to cosmology. We specialize in the development of computational tools for gas dynamics (with and without magnetic fields) and radiative transfer. Simulations using these computer models are run on parallel systems and supercomputers.
