We discuss the merger rate, close galaxy environment, and clustering on scales up to an Mpc of the Swift BAT hard X-ray sample of nearby (z<0.05), moderate-luminosity active galactic nuclei (AGNs). We find a higher incidence of galaxies with signs of disruption compared to a matched control sample (18% versus 1%) and of close pairs within 30 kpc (24% versus 1%). We also find a larger fraction with companions compared to normal galaxies and optical emission line selected AGNs at scales up to 250… Expand

Host Galaxy Properties of the Swift BAT Ultra Hard X-Ray Selected AGN
We have assembled the largest sample of ultra hard X-ray selected (14-195 keV) active galactic nucleus (AGN) with host galaxy optical data to date, with 185 nearby (z 10.5) have a 5-10 times higherExpand
The Swift/BAT AGN Spectroscopic Survey. IX: The Clustering Environments of an Unbiased Sample of Local AGNs
We characterize the environments of local accreting supermassive black holes by measuring the clustering of AGN in the Swift/BAT Spectroscopic Survey (BASS). With 548 AGN in the redshift rangeExpand
Observability of Dual Active Galactic Nuclei in Merging Galaxies
Supermassive black holes (SMBHs) have been detected in the centers of most nearby massive galaxies. Galaxies today are not only the products of billions of years of galaxy mergers, but also billionsExpand
Decreased specific star formation rates in AGN host galaxies
We investigate the location of an ultra-hard X-ray selected sample of AGN from the Swift Burst Alert Telescope (BAT) catalog with respect to the main sequence (MS) of star-forming galaxies usingExpand
The star formation properties of the observed and simulated AGN Universe: BAT versus EAGLE
In this paper we present data from 72 low redshift, hard X-ray selected AGN taken from the Swift-BAT 58 month catalogue. We utilise spectral energy distribution fitting to the optical to IRExpand
Morphologies of z ∼ 0.7 AGN host galaxies in CANDELS: no trend of merger incidence with AGN luminosity
The processes that trigger active galactic nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger disturbances areExpand
Galaxy mergers in eagle do not induce a significant amount of black hole growth yet do increase the rate of luminous AGN
We investigate the connection between galaxy–galaxy mergers and enhanced black hole (BH) growth using the cosmological hydrodynamical eagle simulation. We do this via three methods of analysis,Expand
MAJOR GALAXY MERGERS ONLY TRIGGER THE MOST LUMINOUS ACTIVE GALACTIC NUCLEI
Using multiwavelength surveys of active galactic nuclei (AGNs) across a wide range of bolometric luminosities (1043 < L bol (erg s–1) <5 × 1046) and redshifts (0 < z < 3), we find a strong,Expand
Galaxy pairs in the Sloan Digital Sky Survey – VIII. The observational properties of post-merger galaxies
In order to investigate the effects of galaxy mergers throughout the interaction sequence, we present a study of 10,800 galaxies in close pairs and a smaller sample of 97 post-mergers identified inExpand
The triggering of local AGN and their role in regulating star formation
We explore the processes that trigger local AGN and the role of these AGN in regulating star formation, using ∼550 nearby galaxies observed by the mJy Imaging VLBA Exploration at 20 cm (mJIVE)Expand
