The Evolution of Galaxies in Groups and Clusters
Andrew Wetzel (Yale)

Galaxies in groups and clusters exhibit significantly truncated star formation rates and evolved morphologies. Using galaxy group catalogs created from the Sloan Digital Sky Survey Data Release 7, combined with morphology measurements from the Galaxy Zoo project, I examine the star formation rates and morphologies of satellites galaxies in groups/clusters. I focus on how these galaxy properties depend on satellite mass, group mass, and location within the group. Using cosmological simulations to track satellite galaxy orbits, I test a variety of mechanisms and timescales for satellite galaxy star formation and morphological evolution.
