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…

The Infrared Medium-deep Survey. IV. Low Eddington Ratio of A Faint Quasar at $z \sim 6$ : Not Every Supermassive Black Hole is Growing Fast in the Early Universe

Yongjung Kim, Myungshin Im, Yiseul Jeon +15

To date, most of the luminous quasars known at $z \sim 6$ have been found to be in maximal accretion with the Eddington ratios, $λ_{Edd} \sim 1$ , suggesting enhanced nuclear activ…
