Moving Mesh Astrophysics
Paul Duffell, Postdoctoral Fellow, Theoretical Astrophysics Center, U.C. Berkeley,

This talk will cover a wide range of topics in astrophysics, from the perspective of numerical gas dynamics.  New numerical methods have emerged over the past few years which perform calculations on a generalized mesh, allowing the grid to move with the flow, but while still preserving the desired shock-capturing properties of fixed-grid methods.  The most well-known of these methods uses a Voronoi Tessellation to dynamically re-calculate the shape and size of computational zones as the move through the domain.  I will briefly discuss a few numerical implementations of these techniques, before describing a wide range of applications, including protoplanetary disks, black hole binary systems, tidal disruption events, binary mergers, supernovae and gamma ray bursts.
