Scaling Relations of the Dusty Torus with Luminosity and the Broad-Line Region
Ashraf Ayubinia, Jong-Hak Woo, Shu Wang +2
We measure and compare the size of the dusty torus with active galactic nucleus (AGN) luminosity and the size of the broad-line region (BLR), using a sample of 182 AGNs with the be…

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…
