Abstract

We are conducting the first systematic 3D spectroscopic imaging survey to quantify the properties of the atomic gas (Hi) in a distance-limited sample of 28 Seyfert galaxies and a sample of 28 inactive control galaxies with well-matched optical properties (the VHIKINGS survey). This study aims to address the role of the host galaxy in nuclear activity and confront outstanding controversies in optical/IR imaging surveys. Early results show possible relationships between Seyfert activity and HI extent, content and the prevalence of small, nearby gas-rich dwarf galaxies (M_HI ∼ 10⁷ M_ȯ); results will be tested via rigorous comparison with control galaxies. Initial results from our optical followup study of 15 of our galaxies using the SAURON integral field unit on the WHT suggest a possible difference between Seyfert and inactive stellar and gaseous kinematics that support the conclusion that internal kinematics of galaxies are the key to nuclear activity.
