Exploring Unobscured QSOs in the Southern Hemisphere with KS4
Yongjung Kim, Minjin Kim, Myungshin Im +7
We present a catalog of unobscured QSO candidates in the southern hemisphere from the early interim data of the KMTNet Synoptic Survey of Southern Sky (KS4). The KS4 data covers $\…
The Infrared Medium-deep Survey. VIII. Quasar Luminosity Function at
Yongjung Kim, Myungshin Im, Yiseul Jeon +27
Faint quasars with mag are known to be the potentially important contributors to the ultraviolet ionizing background in the post-reionization era. Howeve…
Medium-band Photometry Reverberation Mapping of Nearby Active Galactic Nuclei
Joonho Kim, Myungshin Im, Changsu Choi +1
Reverberation mapping (RM) is one of the most efficient ways to investigate the broad-line region around the central supermassive black holes of active galactic nuclei (AGNs). A co…
Intensive Monitoring Survey of Nearby Galaxies (IMSNG)
Myungshin Im, Changsu Choi, Sungyong Hwang +46
Intensive Monitoring Survey of Nearby Galaxies (IMSNG) is a high cadence observation program monitoring nearby galaxies with high probabilities of hosting supernovae (SNe). IMSNG a…
The Infrared Medium-deep Survey. VI. Discovery of Faint Quasars at with a Medium-band-based Approach
Yongjung Kim, Myungshin Im, Yiseul Jeon +25
The faint quasars with mag are known to hold the key to the determination of the ultraviolet emissivity for the cosmic re-ionization. But only a few have been identi…
Intra-night optical variability of AGN in the COSMOS field with the KMTNet
Joonho Kim, Marios Karouzos, Myungshin Im +5
Active Galactic Nucleus (AGN) variability can be used to study the physics of the region in the vicinity of the central black hole. In this paper, we investigated intra-night optic…
