MUSE spectroscopy of the compact dual AGN in the radio-loud gravitational lens MG B2016+112
Jianghao Huyan, Júlia M. Sisk-Reynés, Daniel A. Schwartz +4
Dual active galactic nuclei (AGN) are unique laboratories for studying how galaxy mergers trigger accretion onto supermassive black holes (SMBHs). However, at redshifts , only…
AGN-DB: A Unified Multi-Wavelength Database of Active Galactic Nuclei
Alessandro Peca, Nico Cappelluti, C. Megan Urry +29
We present the Active Galactic Nuclei Database (AGN-DB), a comprehensive, multi-wavelength catalog compiled from more than 100 publicly available AGN catalogs and samples released…
Rapid growth in a dual AGN during a gas-rich merger at z~4.5
Hyewon Suh, Roberto Decarli, Emanuele Paolo Farina +15
The late stages of galaxy mergers - when two supermassive black holes (SMBHs) reach kiloparsec-scale separations - represent a critical phase for understanding SMBH growth, galaxy…
Connecting current and future dual AGN searches to LISA and PTA gravitational wave detections
Nianyi Chen, Yihao Zhou, Ekaterine Dadiani +10
Dual active galactic nuclei (DAGN) mark an observable stage of massive black hole (MBH) pairing in galaxy mergers and are precursors to the MBH binaries that generate low-frequency…
The Black Hole Mass and Photometric Components of NGC 4826
Kayhan Gültekin, Karl Gebhardt, John Kormendy +6
We present IR photometry and HST imaging and spectroscopy of Sab galaxy NGC 4826. Schwarzschild dynamical modeling is used to measure its central black hole mass . Photometric d…
A Multiwavelength Portrait of the 3C 220.3 Lensed System
Sóley Ó. Hyman, Belinda J. Wilkes, S. P. Willner +10
The 3C 220.3 system is a rare case of a foreground narrow-line radio galaxy ("galaxy A," ) lensing a background submillimeter galaxy (). New spe…
Uncovering the First AGN Jets with AXIS
Thomas Connor, Eduardo Bañados, Nico Cappelluti +1
Jets powered by AGN in the early Universe () have the potential to not only define the trajectories of the first-forming massive galaxies but to enable the accelerated…
Detecting Wandering Intermediate-Mass Black Holes with AXIS in the Milky Way and Local Massive Galaxies
Fabio Pacucci, Bryan Seepaul, Yueying Ni +2
This white paper explores the detectability of intermediate-mass black holes (IMBHs) wandering in the Milky Way (MW) and massive local galaxies, with a particular emphasis on the r…
X-ray Redshifts for Obscured Active Galactic Nuclei with AXIS Deep and Intermediate Surveys
Alessandro Peca, Nico Cappelluti, Stefano Marchesi +2
This study presents the capabilities of the AXIS telescope in estimating redshifts from X-ray spectra alone (X-ray redshifts, XZs). Through extensive simulations, we establish that…
