Can BLR line profile shape improve single-epoch black hole mass estimates?
Lizvette Villafaña, Tommaso Treu, Shu Wang +7
The virial coefficient (), which is meant to encapsulate broad-line region (BLR) geometry and kinematics, remains one of the largest sources of systematic uncertainty in black h…
Dynamical Modeling of the Broad-Line Region with High-Mass Active Galactic Nuclei and Constraints on the Virial Factor
Shu Wang, Jong-Hak Woo, Lizvette Villafaña +2
We present the results of broad-line region (BLR) dynamical modeling for eight high-mass active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project, by…
Spectroscopic Reverberation Mapping for SARM: The Case of Mrk 1048 and Mrk 618
Shivangi Pandey, Suvendu Rakshit, S. Muneer +14
Robust extragalactic distance measurements are crucial for resolving the persistent discrepancy in the value of the Hubble constant (H)). Active Galactic Nuclei (AGNs), through…
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…
Seoul National University AGN Monitoring Project. V. Velocity-resolved H-beta Reverberation Mapping and Evidence of Kinematics Evolution
Shu Wang, Jong-Hak Woo, Aaron J. Barth +13
We present velocity-resolved reverberation lags of H-beta for 20 active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project. We detect unambiguous velo…
The size of the continuum emission region and its scaling relations with active galactic nucleus luminosity and the broad-line region size
Amit Kumar Mandal, Jong-Hak Woo, Shu Wang
We present a continuum lag analysis for a sample of 37 relatively high-luminosity active galactic nuclei (AGNs) from the Seoul National University AGN Monitoring Project (SAMP), ut…
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…
The Seoul National University AGN Monitoring Project III: H lag measurements of 32 luminous AGNs and the high-luminosity end of the size--luminosity relation
Jong-Hak Woo, Shu Wang, Suvendu Rakshit +28
We present the main results from a long-term reverberation mapping campaign carried out for the Seoul National University Active Galactic Nuclei (AGN) Monitoring Project. High-qual…
