Evolutionary Paths in Galaxy Morphology

Connecting black hole activity and star formation with Galaxy Zoo

Stas Shabala (University of Tasmania)

AGN feedback is a complicated process. Feedback can be imparted in many different ways, and the triggers of AGN activity play an important role in determining the efficiency of the feedback process.

I will show how Galaxy Zoo can provide a unique window on the AGN - star formation connection. Armed with a morphologically-selected sample of early-type galaxies with dust lanes, I will argue that gas-rich galaxy interactions are responsible for triggering radiatively efficient AGN in the local Universe. Using such a clean, morphologically-selected sample allows us to reconstruct the timeline linking star formation and AGN activity.
