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…
The Infrared Medium-deep Survey. \Romannum{7}. Faint Quasars at in the ELAIS-N1 Field
Suhyun Shin, Myungshin Im, Yongjung Kim +26
The intergalactic medium (IGM) at 5 to 6 is largely ionized, and yet the main source for the IGM ionization in the early universe is uncertain. Of the possible contributors…
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…
The Infrared Medium-deep Survey. IV. Low Eddington Ratio of A Faint Quasar at : 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 have been found to be in maximal accretion with the Eddington ratios, , suggesting enhanced nuclear activ…
The Infrared Medium-deep Survey. III. Survey of Luminous Quasars at 4.7 z 5.4
Yiseul Jeon, Myungshin Im, Dohyeong Kim +21
We present our first results of the survey for high redshift quasars at . The search for quasars in this redshift range has been known to be challe…
Discovery of a Supercluster at 0.91 and Testing the CDM Cosmological Model
J. -W. Kim, M. Im, S. -K. Lee +13
The CDM cosmological model successfully reproduces many aspects of the galaxy and structure formation of the universe. However, the growth of large-scale structures (LSSs) in th…
