The first 62 AGN observed with SDSS-IV MaNGA -- III: stellar and gas kinematics [PDF]
, 2019 We investigate the effects of Active Galactic Nuclei (AGN) on the gas kinematics of their host galaxies, using MaNGA data for a sample of 62 AGN hosts and 109 control galaxies (inactive galaxies).

AGN Feedback and Star Formation of Quasar Host Galaxies: Insights from the Molecular Gas [PDF]
Astrophysical Journal, 2020 Molecular gas serves as a key probe of the complex interplay between black hole accretion and star formation in the host galaxies of active galactic nuclei (AGNs). We use CO(2–1) observations from a new Atacama Large Millimeter/submillimeter Array survey,

The triggering probability of radio-loud AGN: A comparison of high and low excitation radio galaxies in hosts of different colors [PDF]
, 2012 Low luminosity radio-loud active galactic nuclei (AGN) are generally found in massive red elliptical galaxies, where they are thought to be powered through gas accretion from their surrounding hot halos in a radiatively inefficient manner.

Effect of bars in AGN host galaxies and black hole activity [PDF]
, 2012 Aims. With the aim of assessing the effects of bars on active galactic nuclei (AGN), we present an analysis of host characteristics and nuclear activity of active galaxies with and without bars. Methods.

The Incidence of Active Galactic Nuclei in Pure Disk Galaxies: The Spitzer View [PDF]
, 2009 We have conducted a high-resolution spectroscopic study using Spitzer of 18 bulgeless (Sd/Sdm) galaxies that show no definitive signatures of nuclear activity in their optical spectra. This is the first systematic mid-IR search for weak or hidden AGNs in

DYNAMICAL EVOLUTION OF AGN HOST GALAXIES—GAS IN/OUT-FLOW RATES IN SEVEN NUGA GALAXIES [PDF]
, 2008 To examine the role of the host galaxy structure in fueling nuclear activity, we estimated gas flow rates from several kpc down to the inner few 10 pc for seven nearby spiral galaxies, selected from the NUclei of GAlaxies sample.

Establishing the impact of powerful AGN on their host galaxies [PDF]
Proceedings of the International Astronomical Union, 2019 AbstractEstablishing the role of active galactic nuclei (AGN) during the formation of galaxies remains one of the greatest challenges of galaxy formation theory. Towards addressing this, we summarise our recent work investigating: (1) the physical drivers of ionised outflows and (2) observational signatures of the impact by jets/outflows on star ...

X-RAY SELECTED AGN HOST GALAXIES ARE SIMILAR TO INACTIVE GALAXIES OUT TO z = 3: RESULTS FROM CANDELS/CDF-S [PDF]
, 2011 We use multi-band spatially resolved photometry from the Cosmic Assembly Near-IR Deep Legacy Survey in the 4 Ms Chandra Deep Field-South to explore the nuclear and extended colors, color gradients, and stellar populations of the host galaxies of X-ray ...

The Type II AGN-host galaxy connection: insights from the VVDS and VIPERS surveys [PDF]
, 2021 We present a study of optically selected Type II active galactic nuclei (AGN) at 0 . 5 < z < 0 . 9 from the VIPERS and VVDS surveys, to investigate the connection between AGN activity and the physical properties of their host galaxies.

Do Bars Trigger Activity in Galactic Nuclei?
, 2012 We investigate the connection between the presence of bars and AGN activity, using a volume-limited sample of $\sim$9,000 late-type galaxies with axis ratio $b/a>0.6$ and $M_{r} < -19.5+5{\rm log}h$ at low redshift ($0.02\le z\lesssim 0.055$), selected ...
