Dormancy and Reawakening Over Years: Eight New Recurrent Changing-Look AGNs
Shu Wang, Jong-Hak Woo, Elena Gallo +5
We report the discovery of eight new recurrent changing-look (CL) active galactic nuclei (AGNs), including seven re-brightening turn-off AGNs and one fading turn-on AGN. These syst…
The Cosmic Evolution of the Supermassive Black Hole Population: A Hybrid Observed Accretion and Simulated Mergers Approach
Fan Zou, W. N. Brandt, Elena Gallo +4
Supermassive black holes (SMBHs) can grow through both accretion and mergers. It is still unclear how SMBHs evolve under these two channels from high redshifts to the SMBH populati…
Radio Scrutiny of the X-ray-Weak Tail of Low-Mass Active Galactic Nuclei: A Novel Signature of High-Eddington Accretion?
Jeremiah D. Paul, Richard M. Plotkin, W. N. Brandt +6
The supermassive black holes () that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between t…
Identifying changing-look AGNs using variability characteristics
Shu Wang, Jong-Hak Woo, Elena Gallo +7
Changing-look (CL) Active Galactic Nuclei (AGNs), characterized by appearance/disappearance of broad emission lines in the span of a few years, present a challenge for the AGN unif…
