ABSTRACT:
It has been known for more than 30 years that galaxy morphology and star formation rates are correlated with environment. 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 use comparisons of galaxy-scale simulations of ram pressure stripping to observations to understand the physics at work in stripped tails, and as probes of the surrounding medium. In combination with semi-analytic models, that are able to model a large parameter space of orbits, we can pin down both satellite galaxy evolution timescales and the density of the stripping gas.
