    Active galactic nucleus feedback drives the colour evolution of local galaxies by Shabala, S, Kaviraj, S, Silk, J

    Published 2011
    “…We investigate the effects of active galactic nucleus (AGN) feedback on the colour evolution of galaxies found in local (z < 0.2) groups and clusters. …”

    Active galactic nucleus torus models and the puzzling infrared spectrum of IRAS F10214+4724 by Efstathiou, A, Christopher, N, Verma, A, Siebenmorgen, R

    Published 2013
    “…We first present and discuss a grid of smooth active galactic nucleus (AGN) torus models computed with the method of Efstathiou and Rowan-Robinson and demonstrate that the combination of these models and the starburst models of Efstathiou and coworkers, while able to give an excellent fit to the average spectrum of Seyfert 2s and spectra of individual type 2 quasars measured by Spitzer, fails to match the spectral energy distribution of IRAS F10214+4724. …”

    DISCOVERY OF AN ACTIVE GALACTIC NUCLEUS DRIVEN MOLECULAR OUTFLOW IN THE LOCAL EARLY-TYPE GALAXY NGC 1266 by Alatalo, K, Blitz, L, Young, L, Davis, T, Bureau, M, Lopez, L, Cappellari, M, Scott, N, Shapiro, K, Crocker, A, Martin, S, Bois, M, Bournaud, F, Davies, R, de Zeeuw, P, Duc, P, Emsellem, E, Falcon-Barroso, J, Khochfar, S, Krajnovic, D, Kuntschner, H, Lablanche, P, McDermid, R, Morganti, R, Naab, T

    Published 2011
    “…The star formation in NGC 1266 is insufficient to drive the outflow, and thus it is likely driven by the active galactic nucleus. The concentration of the majority of the molecular gas in the central 100pc requires an extraordinary loss of angular momentum, but no obvious companion or interacting galaxy is present to enable the transfer. …”

    UNCOVERING THE DEEPLY EMBEDDED ACTIVE GALACTIC NUCLEUS ACTIVITY IN THE NUCLEAR REGIONS OF THE INTERACTING GALAXY Arp 299 by Alonso-Herrero, A, Roche, P, Esquej, P, Gonzalez-Martin, O, Pereira-Santaella, M, Ramos Almeida, C, Levenson, N, Packham, C, Asensio Ramos, A, Mason, R, Rodriguez Espinosa, J, Alvarez, C, Colina, L, Aretxaga, I, Diaz-Santos, T, Perlman, E, Telesco, C

    Published 2013
    “…The GTC/CC spectroscopy displays evidence of deeply embedded active galactic nucleus (AGN) activity in both nuclei. The GTC/CC nuclear spectrum of NGC 3690/Arp 299-B1 can be explained as emission from AGN-heated dust in a clumpy torus with both a high covering factor and high extinction along the line of sight. …”

    LOCAL LUMINOUS INFRARED GALAXIES. II. ACTIVE GALACTIC NUCLEUS ACTIVITY FROM SPITZER/INFRARED SPECTROGRAPH SPECTRA by Alonso-Herrero, A, Pereira-Santaella, M, Rieke, G, Rigopoulou, D

    Published 2012
    “…We quantify the active galactic nucleus (AGN) contribution to the mid-infrared (mid-IR) and the total infrared (IR, 8-1000 μm) emission in a complete volume-limited sample of 53 local luminous infrared galaxies (LIRGs, L IR = 1011-1012 L ⊙). …”

    Unveiling the central parsec region of an active galactic nucleus: The circinus nucleus in the near-infrared with the very large telescope by Almudhna Prieto, M, Meisenheimer, K, Marco, O, Reunanen, J, Contini, M, Clenet, Y, Davies, R, Gratadour, D, Henning, T, Klaas, U, Kotitanien, J, Leinert, C, Lutz, D, Rouan, D, Thatte, N

    Published 2004
    “…Hotter dust within a 1 pc radius of the center is not detected. The active galactic nucleus (AGN) luminosity required to heat this dust is in the range of X-ray luminosities that have been measured toward the central source. …”

    Near-infrared imaging spectroscopy of IRAS FSC 10214+4724: Evidence for a starburst region around an active galactic nucleus at z=2.3 by Kroker, H, Genzel, R, Krabbe, A, TacconiGarman, L, Tecza, M, Thatte, N, Beckwith, S

    Published 1996
    “…FSC 10214 is a very luminous gravitationally lensed galaxy, which intrinsically contains both a type 1 active galactic nucleus and a more extended star-forming disk. …”
