Title:
Galaxy formation from a computational perspective
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.
