Active galaxies hosting two accreting and merging super-massive black holes (SMBHs) – dual Active Galactic Nuclei (AGN) – are predicted by many current and popular models of black hole-galaxy coevolution. We present here the results of a program that has identified a set of probable dual AGN candidates based on near Infra-red (NIR) Laser Guide-Star Adaptive Optics (LGS AO) imaging with the Keck II telescope. These candidates are selected from a complete sample of radio-quiet Quasistellar…

The Origin of Double-peaked Narrow Lines in Active Galactic Nuclei. IV. Association with Galaxy Mergers
Double-peaked narrow emission lines in active galactic nucleus (AGN) spectra can be produced by AGN outflows, rotation, or dual AGNs, which are AGN pairs in ongoing galaxy mergers. Consequently,
Imaging Spectroscopy of Ionized Gaseous Nebulae around Optically Faint AGNs at Redshift z ∼ 2
We present Keck/OSIRIS laser guide-star assisted adaptive optics (LGSAO) integral-field spectroscopy of [O III] λ5007 nebular emission from 12 galaxies hosting optically faint (R = 20–25; ν L_ν ~
X-Ray Properties of Radio-selected Dual Active Galactic Nuclei
Merger simulations predict that tidally induced gas inflows can trigger kpc-scale dual active galactic nuclei (dAGN) in heavily obscured environments. Previously with the Very Large Array, we have
Subaru Infrared Adaptive Optics-assisted High-spatial-resolution Imaging Search for Luminous Dual Active Galactic Nuclei in Nearby Ultraluminous Infrared Galaxies
We present infrared K'- (2.1 micron) and L'-band (3.8 micron) high-spatial-resolution ( 2 micron are used that should be sensitive to buried AGNs due to small dust extinction effects. For ULIRGs with
Double-peaked Lines, Dual VLBI Components, and Precessing Jets in J1328+2752
In this work, we report a radio galaxy with precessing jets, double-peaked emission lines and the presence of two compact radio components with a projected separation of ∼6 parsec in very long
Dual Supermassive Black Holes at Close Separation Revealed by the Hyper Suprime-Cam Subaru Strategic Program
The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized to search for dual
Galaxy Mergers up to z < 2.5. II. AGN Incidence in Merging Galaxies at Separations of 3–15 kpc
We present a study of the incidence of active galactic nucleus (AGN) in a sample of major merging systems at 0.3 < z < 2.5. Galaxies in this merger sample have projected separations between 3 and 15
The role of scatter and satellites in shaping the large-scale clustering of X-ray AGN as a function of host galaxy stellar mass
The co-evolution between central supermassive black holes (BHs), their host galaxies, and dark matter haloes is still a matter of intense debate. Present theoretical models suffer from large
Constraining sub-parsec binary supermassive black holes in quasars with multi-epoch spectroscopy – III. Candidates from continued radial velocity tests
Quasars whose broad emission lines show temporal, bulk radial velocity (RV) shifts have been proposed as candidate sub-parsec (sub-pc), binary supermassive black holes (BSBHs). We identified a sample
