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…
Revisiting the dust torus size-luminosity relation based on a uniform reverberation mapping analysis
Amit Kumar Mandal, Jong-Hak Woo, Shu Wang +4
We investigate the torus size -- luminosity relation of Type 1 AGNs based on the reverberation-mapping analysis using the light curves of the optical continuum and the IR continuum…
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…
