It has long been known that AGN activity is often associated with star-formation in galaxies. However it remains unclear the extent to which feedback from the AGN regulates this star-formation. There is a growing body of circumstantial evidence from models of galaxy formation & evolution that such feedback is required to quench star formation in the largest galaxies, and to inhibit the cooling of gas in clusters of galaxies (the 'cooling flow' problem). Direct observations of feedback in action are, however, hard to come by.


The purpose of this meeting is to bring together theorists, simulators, and observers to discuss the latest advances in each field and to encourage future collaboration.
