New Advances in Astrophysical Simulation

Astrophysical objects such as galaxies, clusters of galaxies, and star-forming gas clouds are so physically complicated that their formation and evolution can only be modeled through computer simulations. I\'ll present some computer simulation techniques currently used to model astrophysical systems, such as N-body, fluid dynamics, and smoothed particle hydrodynamics simulations, and discuss the methodologies adapted from computer science that make these techniques work. I\'ll then reveal some future directions and computer science challenges associated with next generation astrophysical simulations.


Dr. Robertson is an Assistant Professor in the Department of Astronomy at the University of Arizona. His research interests include theoretical topics related to galaxy formation, dark matter, hydrodynamics, and numerical simulation methodologies.

Dr. Robertson previously held a Hubble Fellowship in the Astronomy Department at the California Institute of Technology and a Spitzer Fellowship at the Kavli Institute for Cosmological Physics and Enrico Fermi Institute at the University of Chicago. He earned his Ph.D. in Astronomy from Harvard University in 2006, and received his B.S. in Physics and Astronomy at the University of Washington, Seattle in 2001.
