Galaxy Evolution in Dense Environments

As the universe evolves star-forming galaxies transform into
passively-evolving red galaxies. These transformations are due to a
combination of internal processes, like feedback from an active
galactic nucleus, as well as environmental processes. I will review
the ways in which host environment can affect the properties of
galaxies and then present some of our recent work on group and cluster
galaxies in the local universe. Previous work has found that the star
formation rates of satellite galaxies depend on the mass of their host
halo. We explore how galaxy quenching depends on the evolutionary
state of their host environment as traced by both member dynamics and
X-ray properties. I will discuss how these trends can be used to
constrain the mechanisms at play in environmentally-driven galaxy
evolution and end with some recent work on ram pressure stripped
galaxies in low-redshift clusters.
