Does the Radiative Avalanche Fueling Work in Any Active Galactic Nuclei ?
Recently Umemura, Fukue, & Mineshige (1997) proposed the radiative avalanche fueling to active galactic nuclei; gas accretion is driven by radiation drag exerted by stellar radiation from circumnuclear starburst regions. This mechanism is also interesting in terms of starburst-AGN connections. We therefore present observational tests for the radiative avalanche fueling. Our tests, however, show...
متن کاملFueling of Active Galactic Nuclei
Radiation pressure from the absorption and scattering of starlight by dust grains may be a crucial feedback mechanism in starburst galaxies and the self-gravitating parsec-scale disks that accompany the fueling of active galactic nuclei. I review the case for radiation pressure in both optically-thin and highly optically-thick contexts. I describe the conditions for which Eddington-limited star...
متن کاملOn Bars, Bulges, and the Fueling of Active Galactic Nuclei
Both the fueling of a central black hole and the buildup of bulges are—at least theoretically—facilitated by nonaxisymmetric potentials. It is argued here that the recently established surface brightness division between bulgedominated galaxies that dominate the local type 2 active galactic nucleus (AGN) luminosity function and diskdominated galaxies that host (at best) weak AGNs can be underst...
متن کاملThe Role of Inner Density Waves in Fueling Galactic Nuclei
I present here a heterogeneous selection of galaxies in which inner density waves (bars, spirals, m = 1 modes) have been observed, and which are presumed to host a supermassive black hole.
متن کاملTelescope Observations of the CfA Seyfert 2 s : The Fueling of Active Galactic Nuclei
We present an investigation of possible fueling mechanisms operating in the inner kiloparsec of Seyfert galaxies. We analyze visible and near-infrared Hubble Space Telescope images of 24 Seyfert 2s from the CfA Redshift Survey sample. In particular, we are searching for the morphological signatures of dynamical processes reponsible for transporting gas from kiloparsec scales into the nucleus. T...
