Globular clusters (GCs) are among the oldest known stellar populations, and their ubiquity across a wide range of galaxy luminosity and morphology points to a nearly universal early epoch of star formation. I will present new results from the most comprehensive survey of extragalactic globular cluster systems to date: The ACS Virgo Cluster Survey (ACSVCS). The ACSVCS is a Large HST/ACS program that has imaged 100 early-type galaxies in the Virgo Cluster, from giants to dwarfs, and has produced a catalog of ~11,000 GCs. I will discuss the metallicities and formation efficiencies of these GCs, how they relate to their hosts and environment, and implications for the hierarchical formation of galaxies.
Colloquia are usually preceded by coffee and followed by an informal reception (both in room CSS 0254). Anyone interested in having lunch or talking with the speaker should contact either of the colloquium coordinators (see below). The hour immediately after lunch will normally be reserved for the speaker to talk to graduate students. Students are urged to contact the coordinator to arrange this.
