The Role of "Wimpy" AGNs in Shaping the Evolution of their Host Galaxies
Presented by Kristina Nyland (NMT/NRAO)
One of the most pressing issues in current models of galaxy formation and evolution is the role of active galactic nuclei (AGNs) in shaping the characteristics of their host galaxies. Strong evidence is mounting that AGN feedback from energetic quasar winds and powerful radio jets can dramatically alter its surroundings. The role of feedback from "wimpy" AGNs in the continued evolution of less extreme galaxies is much less clear, but nearby case studies such as NGC 1266 have recently provided us with critical insights. I present the results of a new radio continuum and spectral line study of the AGN and outflow in NGC 1266 that suggests that even low-level AGNs may be able to significantly affect their host galaxies. I also discuss plans for future studies that will be able to put wimpy AGN feedback into the proper evolutionary context.
