Research Title

The Scylla Research Project

Description of Research

The Scylla research project is comparing different numerical codes used to model galaxy formation by running six different codes on the same initial conditions. By studying how the simulated galaxies from each code differ an idea of the total theoretical uncertainty in our understanding of galaxy formation can be established. Differences between models can be used to understand the effects of differing physics and physical implementation.
