NUGA: the IRAM survey of AGN spiral hosts
  The NUclei of GAlaxies (NUGA) project is a combined effort to carry out a high-resolution (<1'') interferometer CO survey of a sample of 12 nearby AGN spiral hosts, using the IRAM array. We map the distribution and dynamics of molecular gas in the inner 1 kpc of the nuclei with resolutions of 10-50 pc, and study the mechanisms for gas fueling of the different low-luminosity AGN. First results show evidence for the occurrence of strong m=1 gas instabilities in Seyferts. NUGA maps allow us to address the origin/nature of m=1 modes and their link with m=2 modes and acoustic instabilities, present in other targets.
