Abstract
Numerical
simulations on supercomputers play an ever more important role in
astrophysics. They have become the tool of choice to predict the
non-linear outcome of the initial conditions left behind by the Big
Bang, providing crucial tests of cosmological theories. However, the
problem of galaxy and star formation confronts us with a staggering
multi-physics complexity and an enormous dynamic range that severely
challenges existing numerical methods. In my talk, I review current
strategies to address these problems, focusing on recent developments in
the field such as hierarchical time integration schemes, improved
particle- and mesh-based hydrodynamical solvers, and novel
parallelization schemes.
Short Biography
Volker Springel
became professor for Theoretical Astrophysics at Heidelberg University
in 2010, where he now leads a research group at the Heidelberg Institute
for Theoretical Studies (HITS). Springel previously was a group leader
in computational cosmology at the Max-Planck-Institute for Astrophysics
in Garching, after working as a postdoctoral researcher at the Harvard
Center for Astrophysics in the United States. He received his PhD in
2000 from the Ludwig-Maximilian University in Munich, after studying
physics at the University of Tübingen and the University of California,
Berkeley.
Chair: Ben Moore (University of Zurich, Switzerland)
