Search of Intermediate Mass Black Holes at Low Redshift with Intra-night Variability
Lael Shin, Jong-Hak Woo, Donghoon Son +4
We present a sample of intermediate-mass black hole (IMBH) candidates based on the detection of a broad H emission line and variability, which are selected from the Sloan Digita…
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…
GECKO Optical Follow-up Observation of Three Binary Black Hole Merger Events: GW190408_181802, GW190412, and GW190503_185404
Joonho Kim, Myungshin Im, Gregory S. H. Paek +12
We present optical follow-up observation results of three binary black hole merger (BBH) events, GW190408_181802, GW190412, and GW190503_185404, which were detected by the Advanced…
