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…

The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies

Lizvette Villafaña, Peter R. Williams, Tommaso Treu +62

We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring…

The Lick AGN Monitoring Project 2016: Velocity-Resolved Hβ Lags in Luminous Seyfert Galaxies

Vivian U, Aaron J. Barth, H. Alexander Vogler +61

We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3-m Shane telescope at Lick Observatory from April 2016 to M…

Unraveling the complex structure of AGN-driven outflows: V. Integral-field spectroscopy of 40 moderate-luminosity Type-2 AGNs

Rongxin Luo, Jong-Hak Woo, Marios Karouzos +6

There is an ongoing debate on whether feedback from active galactic nuclei (AGNs) can effectively regulate the star formation activities in their host galaxies. To investigate the…

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…

Reverberation Mapping of PG 0934+013 with the Southern African Large Telescope

S. Park, J. -H. Woo, E. Romero-Colmenero +10

We present the variability and time lag measurements of PG 0934+013 based on a photometric and spectroscopic monitoring campaign over a two year period. We obtained 46 epochs of da…

Discovery of five low luminosity active galactic nuclei at the centre of the Perseus cluster

Songyoun Park, Jun Yang, J. B. Raymond Oonk +1

According to optical stellar kinematics observations, an over-massive black hole candidate has been reported by van den Bosch et al. (2012) in the normal early-type galaxy NGC 1277…

The black hole mass - stellar velocity dispersion relation of narrow-line Seyfert 1 galaxies

Jong-Hak Woo, Yosep Yoon, Songyoun Park +2

Narrow-line Seyfert 1 galaxies (NLS1s) are arguably one of the key AGN subclasses in investigating the origin of the black hole mass - stellar velocity dispersion (M-sigma) relatio…

The relationship between radio power at 22 and 43 GHz and black hole properties of AGN in elliptical galaxies

Songyoun Park, Bong Won Sohn, Sukyoung K. Yi

We investigate the relationship between radio power and properties related to active galactic nuclei (AGNs). Radio power at 1.4 or 5 GHz, which has been used in many studies, can b…
