    The AGN-Host Galaxy Connection: Environment, Dynamics and Cosmic Indigestion

    Prof. Carole Mundell, Astrophysics Research Institite, Liverpool John Moores University

An outstanding issue in modern astrophysics is the relationship between supermassive black holes and galaxy evolution. Until recently, the study of galaxies (dominated by star-light) and Active Galactic Nuclei (dominated by non-thermal radiation from black-hole accretion), were unconnected disciplines. It is now accepted that bulge-dominated galaxies harbor black holes, thus linking nuclear activity and galaxy evolution in the early Universe. However, the black-hole triggering/fuelling mechanisms, role of the host galaxy and origin of fuel remain unknown. I will present an observational study of the environment and dynamics of nearby galaxies, active and quiescent, that aims to address these issues.
