Many areas of astrophysics now rely on computational techniques to study the dynamical evolution of complex physical systems. Computational simulations are required to be both accurate and timely. To keep up with these demands, the field of Computational Astrophysics is committed to constantly extending existing techniques and developing innovative, new approaches to capture ever more complex physics in computer simulations.
In Steward there is cutting edge computational work being undertaken to better understand how galaxies grow and how the large scale structure of the Universe evolves. There are also efforts to understand the heating impact of turbulent flows in several astrophysical contexts, and the radiative transfer near black holes and neutron stars.
Department members have access to the high-performance computer El Gato [1].
Faculty and Research Staff with a research interest in this area include:
