Galaxy Zoo: the effect of bar-driven fuelling on the presence of an active galactic nucleus in disc galaxies [PDF]
, 2015 We study the influence of the presence of a strong bar in disc galaxies which host an active galactic nucleus (AGN). Using data from the Sloan Digital Sky Survey and morphological classificationsfromtheGalaxyZoo2project,wecreateavolume ...

A TWO-PARAMETER MODEL FOR THE INFRARED/SUBMILLIMETER/RADIO SPECTRAL ENERGY DISTRIBUTIONS OF GALAXIES AND ACTIVE GALACTIC NUCLEI [PDF]
, 2014 A two-parameter semi-empirical model is presented for the spectral energy distributions of galaxies with contributions to their infrared–submillimeter–radio emission from both star formation and accretion disk-powered activity.

The Host Galaxies and Progenitors of Fast Radio Bursts Localized with the Australian Square Kilometre Array Pathfinder [PDF]
2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020 The Australian SKA Pathfinder (ASKAP) telescope has started to localize fast radio bursts (FRBs) to arcsecond accuracy from the detection of a single pulse, allowing their host galaxies to be reliably identified.

EVIDENCE FOR WIDE-SPREAD ACTIVE GALACTIC NUCLEUS-DRIVEN OUTFLOWS IN THE MOST MASSIVE z ∼ 1–2 STAR-FORMING GALAXIES [PDF]
, 2014 In this paper, we follow up on our previous detection of nuclear ionized outflows in the most massive (log(M*/M☉) ⩾ 10.9) z ∼ 1–3 star-forming galaxies by increasing the sample size by a factor of six (to 44 galaxies above log(M*/M☉) ⩾ 10.9) from a ...

Radio-continuum sources in nearby and bright E/S0 galaxies: active nuclei versus star formation
, 1991 Results of a sensitive VLA survey of nearby E/S0 galaxies are presented. The 204 galaxies surveyed, plus 12 additional galaxies with existing VLA images, comprise a volume- and optical magnitude-limited sample.

FROM STARBURST TO QUIESCENCE: TESTING ACTIVE GALACTIC NUCLEUS FEEDBACK IN RAPIDLY QUENCHING POST-STARBURST GALAXIES [PDF]
, 2014 Post-starbursts are galaxies in transition from the blue cloud to the red sequence. Although they are rare today, integrated over time they may be an important pathway to the red sequence.

Determining Central Black Hole Masses in Distant Active Galaxies and Quasars. II. Improved Optical and UV Scaling Relationships [PDF]
, 2002 We present four improved empirical relationships useful for estimating the central black hole mass in nearby AGNs and distant luminous quasars alike using either optical or UV single-epoch spectroscopy.

DWARF GALAXIES WITH OPTICAL SIGNATURES OF ACTIVE MASSIVE BLACK HOLES [PDF]
, 2013 We present a sample of 151 dwarf galaxies (108.5 ≲ M⋆ ≲ 109.5 M☉) that exhibit optical spectroscopic signatures of accreting massive black holes (BHs), increasing the number of known active galaxies in this stellar-mass range by more than an order of ...

Identification of active galaxies behind the Coma cluster of galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 1999 We describe the results of an efficient survey to identify bright B < ∼ 18 active galactic nuclei (AGN) within ≈ 4 • (4.7 h −1 Mpc projected radius) of the centre of the Coma cluster of galaxies. The candidates have been carefully selected either as unresolved UV-excess objects with no detected proper motion, or from identifications on objective-prism ...

BLACK HOLE VARIABILITY AND THE STAR FORMATION–ACTIVE GALACTIC NUCLEUS CONNECTION: DO ALL STAR-FORMING GALAXIES HOST AN ACTIVE GALACTIC NUCLEUS? [PDF]
, 2013 We investigate the effect of active galactic nucleus (AGN) variability on the observed connection between star formation and black hole accretion in extragalactic surveys.
