Dwarf AGNs from Optical Variability for the Origins of Seeds (DAVOS): Insights from the Dark Energy Survey Deep Fields
Colin J. Burke, Xin Liu, Yue Shen +69
We present a sample of 706, active galactic nuclei (AGNs) selected from optical photometric variability in three of the Dark Energy Survey (DES) deep fields (E2, C3, and…
Investigating the Accretion Nature of Binary Supermassive Black Hole Candidate SDSS J025214.67-002813.7
Adi Foord, Xin Liu, Kayhan Gültekin +3
We present results on a multi-wavelength analysis of SDSS J025214.67-002813.7, a system which has been previously classified as a binary AGN candidate based on periodic signals det…
Small-scale double quasars discovered in the DECam Legacy Survey
Yu-Ching Chen
Dual quasars are precursors of binary supermassive black holes, which are important objects for gravitational wave study, galaxy evolution, and cosmology. I report four double quas…
Varstrometry for Off-nucleus and Dual sub-Kpc AGN (VODKA): Hubble Space Telescope Discovers Double Quasars
Yu-Ching Chen, Hsiang-Chih Hwang, Yue Shen +4
Dual supermassive black holes (SMBHs) at kpc scales are the progenitor population of SMBH mergers and play an important role in understanding the pairing and dynamical evolut…
A hidden population of high-redshift double quasars unveiled by astrometry
Yue Shen, Yu-Ching Chen, Hsiang-Chih Hwang +6
Galaxy mergers occur frequently in the early universe and bring multiple supermassive black holes (SMBHs) into the nucleus, where they may eventually coalesce. Identifying post-mer…
Very Large Array imaging rules out precessing radio jets in three DESSDSS-selected candidate periodic quasars
Yu-Ching Chen, Xin Liu, Wei-Ting Liao +1
Periodic quasars have been suggested as candidates for hosting binary supermassive black holes (SMBHs), although alternative scenarios remain possible to explain the optical light…
