Globular cluster systems and the early evolution of galaxies

Globular clusters are among the oldest stellar populations in the local Universe, thus providing a unique window onto the earliest epochs of galaxy formation. As markers of the most intense periods of star formation, these old, massive star clusters are intricately entwined with the formation of the galaxies that host them. Some of their properties, but not all, mirror those of their host galaxies, and it is from both the similarities and differences that we can gain insight on galaxy evolution. I will present a view of globular cluster systems in 100 early-type galaxies from the ACS Virgo Cluster Survey, the most comprehensive and homogeneous data set of its type to date. I will describe some of the main results of the survey, including the metallicities and specific frequencies of our surveyed globular cluster systems, and discuss their implications for early galaxy formation.
