Outflows @ UCSB


● Overview

The Southern California Center for Galaxy Evolution (CGE) presents a workshop on galaxy outflows to be held at UC Santa Barbara on August 19 and 20, 2013. The purpose is to bring together a small group of astronomers for two days of short talks, group discussions, and open time for one-on-one and small group interaction. The broad topic is the physical nature of outflows / feedback and their effect on galaxies and their surrounding medium, including perspectives from all aspects of theory and observations.
