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 H Size-Luminosity Relation Using a Uniform Reverberation-Mapping Analysis
Shu Wang, Jong-Hak Woo
We revisit the relation between active galactic nucleus (AGN) broad-line region (BLR) size and luminosity by conducting a uniform H reverberation-mapping analysis for 212 AGNs w…
Prior-Informed AGN-Host Spectral Decomposition Using PyQSOFit
Wenke Ren, Hengxiao Guo, Yue Shen +4
We introduce an improved method for decomposing the emission of active galactic nuclei (AGN) and their host galaxies using templates from principal component analysis (PCA). This a…
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…
