Discovery of A Faint Quasar at z~6 and Implications for Cosmic Reionization

Yongjung Kim, Myungshin Im, Yiseul Jeon +15

Recent studies suggest that faint active galactic nuclei may be responsible for the reionization of the universe. Confirmation of this scenario requires spectroscopic identificatio…

The Very Early Light Curve of SN 2015F in NGC 2442: A Possible Detection of Shock-Heated Cooling Emission and Constraints on SN Ia Progenitor System

Myungshin Im, Changsu Choi, Sung-Chul Yoon +4

The main progenitor candidate of Type Ia supernovae (SNe Ia) is white dwarfs in binary systems where the companion star is another white dwarf (double degenerate system) or a less…

Evolution of Star-formation Properties of High-redshift Cluster Galaxies since

Seong-Kook Lee, Myungshin Im, Jae-Woo Kim +4

Using a stellar mass limited sample of galaxies () at , we show that the tellar mass, rather than the environment, is the main…

Linking galaxies to dark matter haloes at : dependence of galaxy clustering on stellar mass and specific star formation rate

Jae-Woo Kim, Myungshin Im, Seong-Kook Lee +4

We study the dependence of angular two-point correlation functions on stellar mass () and specific star formation rate (sSFR) of galaxies at $z\sim1…

CF-HiZELS, a 10 deg emission-line survey with spectroscopic follow-up: Hα, [OIII]+Hβ and [OII] luminosity functions at z=0.8, 1.4 and 2.2

David Sobral, Jorryt Matthee, Philip N. Best +8

We present results from the largest contiguous narrow-band survey in the near-infrared. We have used WIRCam/CFHT and the lowOH2 filter (1.1870.005 m) to survey ~10 deg…
