Modeling Early Galaxies Using Radiation Hydrodynamics

Project StarGate Application Driver
[ click above image for streaming video]

This simulation uses a flux-limited diffusion solver to explore the radiation hydrodynamics of early galaxies, in particular, the ionizing radiation created by Population III stars. At the time of this rendering, the simulation has evolved to a redshift of 3.5. The simulation volume is 11.2 comoving megaparsecs, and has a uniform grid of 1024^3 cells, with over 1 billion dark matter and star particles.

The simulation was computed on resources of the National Institute for Computational Sciences, with support from the National Science Foundation under TeraGrid award TG-MCA98N020.

The visualization was produced using resources of the Argonne Leadership Computing Facility at Argonne National Laboratory, which is supported by the Office of Science of the U.S. Department of Energy under contract DE-AC02-06CH11357.
