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

“…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. …”

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

“…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. …”

The atlas 3D Project – XXXI. Nuclear radio emission in nearby early-type galaxies by Nyland, K, Young, L, Wrobel, J, Sarzi, M, Morganti, R, Alatalo, K, Blitz, L, Bournaud, F, Bureau, M, Cappellari, M, Crocker, A, Davies, R, Davis, T, de Zeeuw, P, Duc, P, Emsellem, E, Khochfar, S, Krajnović, D, Kuntschner, H, McDermid, R, Naab, T, Oosterloo, T, Scott, N, Serra, P, Weijmans, A

“…Based on the radio continuum properties, as well as optical emission line diagnostics and the nuclear X-ray properties, we conclude that the majority of the central 5 GHz sources detected in the ATLAS3D galaxies are associated with the presence of an active galactic nucleus (AGN). However, even at subarcsecond spatial resolution, the nuclear radio emission in some cases appears to arise from low-level nuclear star formation rather than an AGN, particularly when molecular gas and a young central stellar population is present. …”

FAST MOLECULAR OUTFLOWS IN LUMINOUS GALAXY MERGERS: EVIDENCE FOR QUASAR FEEDBACK FROM HERSCHEL by Veilleux, S, Melendez, M, Sturm, E, Gracia-Carpio, J, Fischer, J, Gonzalez-Alfonso, E, Contursi, A, Lutz, D, Poglitsch, A, Davies, R, Genzel, R, Tacconi, L, de Jong, J, Sternberg, A, Netzer, H, Hailey-Dunsheath, S, Verma, A, Rupke, D, Maiolino, R, Teng, S, Polisensky, E

“…While the outflow velocities show no statistically significant dependence on the star formation rate, they are distinctly more blueshifted among systems with large active galactic nucleus (AGN) fractions and luminosities [log (L AGN/L⊙) ≥ 11.8 ± 0.3]. …”

“…In NGC 4418, we argue that X-ray ionization due to an active galactic nucleus is responsible for the molecular ion production. © 2013 ESO.…”

NGC 1266 AS A LOCAL CANDIDATE FOR RAPID CESSATION OF STAR FORMATION by Alatalo, K, Nyland, K, Graves, G, Deustua, S, Griffin, K, Duc, P, Cappellari, M, McDermid, R, Davis, T, Crocker, A, Young, L, Chang, P, Scott, N, Cales, S, Bayet, E, Blitz, L, Bois, M, Bournaud, F, Bureau, M, Davies, R, de Zeeuw, P, Emsellem, E, Khochfar, S, Krajnovic, D, Kuntschner, H

“…Galaxies with K+A spectra and shock-like ionized gas line ratios may comprise an important, overlooked segment of the poststarburst population, containing exactly those objects in which the active galactic nucleus (AGN) is actively expelling the star-forming material. …”

HERSCHEL-PACS OBSERVATIONS OF FAR-IR CO LINE EMISSION IN NGC 1068: HIGHLY EXCITED MOLECULAR GAS IN THE CIRCUMNUCLEAR DISK by Hailey-Dunsheath, S, Sturm, E, Fischer, J, Sternberg, A, Gracia-Carpio, J, Davies, R, Gonzalez-Alfonso, E, Mark, D, Poglitsch, A, Contursi, A, Genzel, R, Lutz, D, Tacconi, L, Veilleux, S, Verma, A, de Jong, J

“…The blueshift of the HE lines may also be consistent with the bluest regions of this H2 ring, but a better kinematic match is found with a clump of infalling gas 40pc north of the active galactic nucleus (AGN). We consider potential heating mechanisms and conclude that X-ray- or shock heating of both components is viable, while far-UV heating is unlikely. …”
