Fading AGN Candidates: AGN Histories and Outflow Signatures
William C. Keel, Chris J. Lintott, W. Peter Maksym +12
We consider energy budgets and radiative history of 8 fading AGN, identified from mismatch between the ionizion of very extended (>10 kpc) ionized clouds and the luminosity of the…
Active Galactic Nuclei from HeII: a more complete census of AGN in SDSS galaxies yields a new population of low-luminosity AGN in highly star-forming galaxies
Rudolf Bär, Anna K. Weigel, Lia F. Sartori +3
In order to perform a more complete census of active galactic nuclei (AGN) in the local Universe, we investigate the use of the HeII~ emission line diagnostic diagram by Shi…
Unveiling multiple AGN activity in galaxy mergers
A. De Rosa, S. Bianchi, T. Bogdanovic +13
In this paper we present an overview of the MAGNA (Multiple AGN Activity) project aiming at a comprehensive study of multiple supemassive black hole systems. With the main goal to…
Galaxy Zoo: Morphological Classifications for 120,000 Galaxies in HST Legacy Imaging
Kyle W. Willett, Melanie A. Galloway, Steven P. Bamford +18
We present the data release paper for the Galaxy Zoo: Hubble (GZH) project. This is the third phase in a large effort to measure reliable, detailed morphologies of galaxies by usin…
Galaxy Zoo: Quantitative Visual Morphological Classifications for 48,000 galaxies from CANDELS
B. D. Simmons, Chris Lintott, Kyle W. Willett +45
We present quantified visual morphologies of approximately 48,000 galaxies observed in three Hubble Space Telescope legacy fields by the Cosmic And Near-infrared Deep Extragalactic…
BAT AGN Spectroscopic Survey-III. An observed link between AGN Eddington ratio and narrow emission line ratios
Kyuseok Oh, Kevin Schawinski, Michael Koss +14
We investigate the observed relationship between black hole mass (), bolometric luminosity (), and Eddington ratio () with optical emission li…
