Title Cosmological simulations of galaxy formation

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.
