The NUGA Project
In most Active Galactic Nuclei (AGN) the activity of the nucleus is powered by accretion of matter onto a super-massive black hole. The "NUclei of GAlaxies" project (NUGA) investigates the gas dynamics from the outskirts of spiral galaxies to the very center in order to understand the inflow mechanisms and their relations to AGN and galaxy evolution scenarios. This work is based on high resolution observations of emission lines from neutral (HI) and molecular gas (CO) with interferometers operating at radio and millimeter frequencies, respectively (NRAO Very Large Array and IRAM Plateau de Bure Interferometer).
