The Triggering Mechanisms for Active Galactic Nuclei
Description and Aim
2013 marks the 50th anniversary of the optical identification of quasars. Since their discovery, our view of these extreme AGN has changed substantially: whereas they were once thought of as exotic objects that were useful because their high luminosities allowed them to be used as probes of the high-z Universe, they are now considered central to our overall understanding of the evolution of massive galaxies. However, we know surprisingly little about how and when quasars are triggered as galaxies evolve.
The aim of this workshop is to bring together all the latest observational and theoretical results on AGN triggering across the full range of AGN luminosity, in order to address the following issues.
· What are the dominant modes of triggering of AGN?
· Is there a dichotomy in triggering mechanisms between high and moderate luminosity AGN?
· What physical processes deliver the gas from a sub-kpc to a pc-scale?
· Do the dominant triggering mechanisms change with cosmic epoch?
· Has the environment any influence on how AGN are triggered?
