Title | Cosmological simulations of galaxy formation |
Abstract |
Galaxy formation simulations have made significant progresses in the last ten years. Although the quantitative agreement between cosmological simulations and observed galaxy properties has improved, many problems remain. I will present some recent work on computational galaxy formation using adaptive mesh refinement techniques. I will focus on the important role played by subgrid models such as star formation efficiencies and supernovae feedback recipes. Going beyond these simplified models requires a much better resolution. I will show some recent high resolution simulations of high redshift galaxies and merging galaxies that suggest that new insights on the physics of galaxy formation can be indeed obtained. |
