28 Oct 2003 | | Subject: | astro-ph | | Abstract: | 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. | | Source: | arXiv, astro-ph/0310797 | | Services: | Forum | Review | PDF | Favorites | |
