The Hunt for Red Dual AGNs I: Spatially-Resolved Mid-IR Dual AGNs in the DeCam Legacy Survey
Ryan W. Pfeifle, Kimberly A. Weaver, Barry Rothberg +13
Theoretical studies predict that dual AGNs are a critical stage of galaxy merger-driven supermassive black hole growth. Systematic searches for dual AGNs typically target late-stag…
A High Resolution Search for Dual AGN Candidates in Mergers: A Pre-Selection Strategy using Keck AO
Camilo Vazquez, S. Satyapal, G. Canalizo +20
Accreting supermassive black holes (SMBHs) in galaxy mergers with separations 1 kpc are crucial to our understanding of SMBH growth, galaxy evolution, and SMBH binary evolution…
Clustering properties of the CatWISE2020 quasar catalogue and their impact on the cosmic dipole anomaly
Sebastian von Hausegger, Nathan Secrest, Harry Desmond +3
The cosmic dipole anomaly -- the observation of a significant mismatch between the dipole observed in the matter distribution and that expected given the kinematic interpretation o…
VLA FRAMEx. III. Circumnuclear Radio Emission Mechanisms in Hard X-ray Selected Active Galactic Nuclei
Andrew J. Sargent, Alexander J. van der Horst, Megan C. Johnson +5
We present Stokes I continuum analysis for a volume-limited sample () of hard X-ray selected active galactic nuclei (AGNs) using GHz observations with the Karl…
VLA FRAMEx. II. Radio Spectra of Nearby Active Galactic Nuclei at Subarcsecond Resolution
Andrew J. Sargent, Alexander J. van der Horst, Megan C. Johnson +5
We present GHz in-band spectral energy distributions with accompanying 6 GHz and 10 GHz imaging results for a volume-complete sample ( Mpc) of hard X-ray selected activ…
Varstrometry for Dual AGN using Radio interferometry: VaDAR with the VLBA
Emma Schwartzman, Paula Fudolig, Tracy Clarke +6
Multiple active galactic nuclei (multi-AGN) are a known result of galaxy mergers. Therefore, they are an important tool for studying the formation and dynamical evolution of galaxi…
