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. …”

DETECTION OF A HIGH BRIGHTNESS TEMPERATURE RADIO CORE IN THE ACTIVE-GALACTIC-NUCLEUS-DRIVEN MOLECULAR OUTFLOW CANDIDATE NGC 1266 by Nyland, K, Alatalo, K, Wrobel, J, Young, L, Morganti, R, Davis, T, de Zeeuw, P, Deustua, S, Bureau, M

On the depletion and accretion timescales of cold gas in local early-type galaxies by Davis, T, Bureau, M

“…To reproduce that distribution, both fast gas depletion (tdep ≲ 108 yr; e.g. more efficient star formation) and fast gas destruction (e.g. by active galactic nucleus feedback) can be invoked, but both also require a high rate of gas-rich mergers (>1 Gyr−1). …”

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. …”

Delayed triggering of radio active galactic nuclei in gas-rich minor mergers in the local Universe by Shabala, S, Deller, A, Kaviraj, S, Middelberg, E, Turner, R, Ting, Y, Allison, J, Davis, T

“…We examine the processes triggering star formation and active galactic nucleus (AGN) activity in a sample of 25 low-redshift (z < 0.13) gas-rich galaxy mergers observed at milliarcsecond resolution with Very Long Baseline Interferometry (VLBI) as part of the mJy Imaging VLBA Exploration at 20 cm (mJIVE-20) survey. …”

Gemini GMOS and WHT SAURON integral-field spectrograph observations of the AGN-driven outflow in NGC 1266 by Davis, T, Krajnovic, D, McDermid, R, Bureau, M, Sarzi, M, Nyland, K, Alatalo, K, Bayet, E, Blitz, L, Bois, M, Bournaud, F, Cappellari, M, Crocker, A, Davies, R, de Zeeuw, P, Duc, P, Emsellem, E, Khochfar, S, Kuntschner, H, Lablanche, P, Morganti, R, Naab, T, Oosterloo, T, Scott, N, Serra, P

“…We use the Spectrographic Areal Unit for Research on Optical Nebulae and Gemini Multi-Object Spectrograph integral-field spectrographs to observe the active galactic nucleus (AGN) powered outflow in NGC1266. …”

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. …”
