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…

The Seoul National University AGN Monitoring Project IV: H reverberation mapping of 6 AGNs and the H Size-Luminosity Relation

Hojin Cho, Jong-Hak Woo, Shu Wang +29

The broad line region (BLR) size-luminosity relation has paramount importance for estimating the mass of black holes in active galactic nuclei (AGNs). Traditionally, the size of th…

H Reverberation Mapping of the Intermediate-Mass Active Galactic Nucleus in NGC 4395

Hojin Cho, Jong-Hak Woo, Tommaso Treu +24

We present the results of a high-cadence spectroscopic and imaging monitoring campaign of the active galactic nucleus (AGN) of NGC 4395. High signal-to-noise-ratio spectra were obt…

Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395

Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31

We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…

The Seoul National University AGN monitoring project. II. BLR size and black hole mass of two AGNs

Suvendu Rakshit, Jong-Hak Woo, Elena Gallo +20

Active galactic nuclei (AGNs) show a correlation between the size of the broad line region (BLR) and the monochromatic continuum luminosity at 5100 Å, allowing black hole mass esti…

Seoul National University AGN Monitoring Project. I. Strategy and Sample

J. -H. Woo, D. Son, E. Gallo +16

While the reverberation mapping technique is the best available method for measuring black hole mass in active galactic nuclei (AGN) beyond the local volume, this method has been m…
