Receipt: # 68-6 ----- Attempting Submission 7 (Sat Mar 07 01:55:38 GMT 2020) ----- Measuring the fueling and feedback in active galactic nuclei is vital to understanding the co-evolution of galaxies and their massive black holes. We have 0.1" resolution ALMA CO spectroscopic maps of the velocity fields of molecular gas in and around the centers of a representative sample of 48 nearby (d<50Mpc) AGN. We model the rotation with Diskfit revealing residuals from circular motion due to gas inflows and outflows. We propose combining ALMA velocity maps with three observables available only from HST imaging: 1) red starlight to determine the distribution of stellar mass, which determines the gravitational potential; 2) color maps of absorption lanes to show the distribution of dust; and 3) continuum-subtracted narrow-band images of H-alpha+[NII] and [OIII] to measure the distribution of ionized gas. As demonstrated on a few galaxies, this combination of HST measurements of the stellar mass with ALMA velocity fields maps the distribution of stellar torques on gas. Where they are negative, gas flows inward, with a mass rate which we calculate. We will determine if these inflows account for the AGN accretion rate derived from bolometric luminosities; and if gas depletion timescales are comparable to AGN duty cycles. Where we detect outflows, HST images will show their impact on star formation. Our 48-galaxy sample will reveal correlations between gas inflow and outflow properties with the mass and accretion rate of the MBH, the presence of broad lines (direct or hidden), and properties of the host galaxy. We will test predictions that outflow energies are 5% of AGN luminosity. We will also perform this HST+ALMA analysis on a control sample of normal galaxies. The PI has worked with optical and NIR imaging of nearby AGN with HST since the first reservicing mission. This work, particularly emphasizing the distributions of gas and dust around the galactic centers, has produced more than fifteen referreed publications. Prof. Luigi Spinoglio is a staff scientist at the INAF-IAPS in Rome, Italy. His main research topics are: the discovery and exploitation of physical diagnostics of galaxies, using emission lines; the first selection of a sample of galaxies in the mid-IR (1989-1993), which has been the basis of one of the best local samples of AGN; the study and development of the science objectives for future extragalactic and galaxy evolution studies. Currently he is a leader in the exploration of science drivers for the SAFARI spectrometer onboard SPICA, a cryogenic IR telescope designed by ESA/JAXA. He is the scientific coordinator of the Galaxy Evolution Working Group for the SPICA Observatory. Dr. Fernandez-Ontiveros has expertise in observational IR astronomy, from adaptive-optics, to mid-IR interferometry, polarimetry, and IR spectroscopy. In particular, he has extensive experience with the reduction, calibration, and further analysis of Herschel spectroscopy (e.g. Fernandez-Ontiveros et al. 2016). Recently, he led the chemical evolution study of galaxies for the SPICA mission, developing new metallicity tracers, and the observational strategies to exploit them (Fernandez-Ontiveros et al. 2017). Dr. Francoise Combes has worked for decades on galaxy dynamics, particularly showing how torques by stellar bars cause gas to flow in to the centers of galaxies, fueling nuclear activity. In particular she has pioneered the torque computation method from infrared images and gas distribution, to determine actual gas flows in galaxy disks. She has worked intensively on the role of non-axisymmetric features, such as bars and spirals, and also lopsided (m=1) perturbations, to fuel SMBH in galaxies, and determine their various AGN phases. Recently, with the NUGA collaboration, they have revealed the existence of misaligned molecular tori in nearby Seyferts with ALMA. Post-doctoral research fellow Dr. Wayne Webb has worked extensively with optical and IR imaging and photometry of the central regions of nearby Seyfert galaxies (e.g., 2000 ApJ 540, 652; 1999 ApJS 125, 349), and has participated as a Co-investigator on several approved HST programs.
