TAPIR Seminar

It has been known for some time that galaxies in dense environments tend to be redder and of earlier types.  I will discuss my numerical work studying cluster galaxy evolution, arguing that ram pressure stripping is a critical mechanism driving satellite galaxy evolution.  I will also compare cosmological hydrodynamical simulations to observations that find that galaxies in dense environments at z=1 may have higher star formation rates than galaxies in low-density environments.  Finally I will discuss whether the large-scale environment may have an impact on galaxy evolution.
