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…
Prediction of Star Formation Rates Using an Artificial Neural Network
Ashraf Ayubinia, Jong-hak Woo, Fatemeh Hafezianzadeh +2
In this study, we develop an artificial neural network to estimate the infrared (IR) luminosity and star formation rates (SFR) of galaxies. Our network is trained using 'true' IR l…
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…
