Comparison of The UV and Optical Fe II Emission in Type 1 AGNs
Huynh Anh N. Le, Jong-Hak Woo
We present the kinematical properties of the UV and optical \FeII\ emission gas based on the velocity shift and line width measurements of a sample of 223 Type 1 active galactic nu…
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…
X-ray spectral variations of synchrotron peak in BL Lacs
Yijun Wang, Shifu Zhu, Yongquan Xue +3
The spectral energy distribution of blazars around the synchrotron peak can be well described by the log-parabolic model that has three parameters: peak energy (), pe…
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…
A 10,000-solar-mass black hole in the nucleus of a bulgeless dwarf galaxy
Jong-Hak Woo, Hojin Cho, Elena Gallo +5
The motions of gas and stars in the nuclei of nearby large galaxies have demonstrated that massive black holes are common and that their masses strongly correlate with the stellar…
The FeII/MgII flux ratio of low-luminosity quasars at z~3
Jaejin Shin, Tohru Nagao, Jong-Hak Woo +1
The FeII/MgII line flux ratio has been used to investigate the chemical evolution of high redshift active galactic nuclei (AGNs). No strong evolution has been found out to z~6, imp…
