The Impact of Environment on Galaxy Evolution
Stephanie Tonnesen, Postdoctoral Fellow, Carnegie Observatories,

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.
