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…

On the observability of individual Population III stars and their stellar-mass black hole accretion disks through cluster caustic transits

Rogier A. Windhorst, M. Alpaslan, S. Andrews +44

Recent near-IR power-spectra and panchromatic Extragalactic Background Light measurements provide upper limits on the near-IR surface brightness (SB>31 mag/arcsec^2) that may come…

Analysis of the spatially-resolved -3.6m colors and dust extinction in 257 nearby NGC and IC galaxies

Duho Kim, Rolf A. Jansen, Rogier A. Windhorst +2

We present and analyze spatially-resolved maps for the observed - and -band to 3.6m flux ratios and the inferred dust extinction values, , for a sample of 257 nearby…

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…
