The interaction between the nuclear activity in active galactic nuclei (AGN) and their host galaxies is crucial to understand the galaxy formation and evolution. Our aim is to explore the close environment of AGN and its connection to the host galaxy through the morphology and dynamics of the gas inside the central kpc in nearby AGN. Probing the dynamical structures leading to the fuel of the supermassive black hole (SMBH) from hundreds to parsec scales, the duty cycle of gas and the impact of molecular outflows on the star formation is crucial to understand how AGN are fueled in galaxies, and how the energy generated by the active nucleus can in turn regulate gas accretion. We report ALMA observations of a sample of 7 Seyfert/LINER part of the NUGA (NUclei of GAlaxies) project, at the unprecedented spatial resolution of 0.06-0.09'' (3-10 pc). We will present the observed molecular maps that have revealed the existence of molecular tori and show AGN feeding and feedback caught in action in some cases: trailing spirals observed inside the central 100 pc, efficiently driving the molecular gas into the SMBH and the detection of molecular outflows driven by the AGN. |
