The Infrared Medium-deep Survey. VI. Discovery of Faint Quasars at $z \sim 5$ with a Medium-band-based Approach

Yongjung Kim, Myungshin Im, Yiseul Jeon +25

The faint quasars with $M_{1450} > - 24$ 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…
