NUclei of GAlaxies (NUGA): the IRAM Survey of Low Luminosity AGN

The NUGA project is the first high-resolution (0.5’‘-1’') CO survey of low luminosity AGN including the full sequence of activity types (Seyfert 1–2 and LINERs). NUGA aims to study systematically the different mechanisms for gas fueling of the AGN. In order to reach the critical spatial scales for AGN feeding (<100 pc), we are undertaking high-resolution observations, made at the Plateau de Bure Interferometer, to achieve a sharp view of the distribution and kinematics of molecular gas. In this talk we discuss the latest results of this survey which now includes newly acquired subarcsec resolution observations for 5 targets of our sample. The large variety of circumnuclear disk morphologies found in NUGA galaxies (m=1, m=2 and m=0-type gravitational instabilities) is a challenging result that urges the refinement of current dynamical models.
