Special Astronomy Colloquium
Extragalactic Globular Cluster Systems: Relics from the Early Epochs of Galaxy Formation
Time: 3:30 pm
Place: 3425 Sterling Hall
Speaker: Dr. Eric Peng, Kavli Institute for Astronomy and Astrophysics & Peking University
Abstract: Globular clusters are our most easily accessible local window onto the high redshift Universe. Visible out to distances of hundreds of Mpc, they are the "tip of the iceberg" for the oldest stars -- populations which are otherwise extremely difficult to study in distant galaxies.
HST and ground-based surveys of nearby galaxy clusters are transforming our view of these halo populations. I will discuss the ways in which extragalactic globular systems are teaching us about galaxy assembly, and will present recent results from the ACS Virgo and Fornax Cluster Surveys, the HST/ACS Coma Cluster Treasury Survey, and the Next Generation Virgo Survey.
Host: Christy Tremonti
