Abstract

Within the cosmic web, galaxies form as baryonic gas flows along cosmic filaments into dark-matter halos. This gas fuels the formation of stars within galaxies, while the resultant feedback from stars drives strong outflows of gas from galaxies. I will describe how we use massively parallelized cosmological hydrodynamic simulations, run on the largest supercomputers, to model the physics of galaxy formation, including nonlinear gravitational dynamics, hydrodynamics, star formation, and stellar feedback.
