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…

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…

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…

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…
