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…
The North Ecliptic Pole Wide survey of AKARI: a near- and mid-infrared source catalog
Seong Jin Kim, Hyung Mok Lee, Hideo Matsuhara +19
We present a photometric catalog of infrared (IR) sources based on the North Ecliptic PoleWide field (NEP-Wide) survey of AKARI, which is an infrared space telescope launched by Ja…
Discovery and Early Multi-Wavelength Measurements of the Energetic Type Ic Supernova PTF12gzk: A Massive-Star Explosion in a Dwarf Host Galaxy
Sagi Ben-Ami, Avishay Gal-Yam, Alexei V. Filippenko +45
We present the discovery and extensive early-time observations of the Type Ic supernova (SN) PTF12gzk. Our finely sampled light curves show a rise of 0.8mag within 2.5hr. Power-law…
A Y-band look of the sky with 1-m class telescopes
Changsu Choi, Myungshin Im, Yiseul Jeon +1
Y -band is a broad passband that is centered at ~ 1 micron. It is becoming a new, popular window for extragalactic study especially for observation of red objects thanks to recent…
AKARI Observation of the North Ecliptic Pole (NEP) Supercluster at z = 0.087: mid-infrared view of transition galaxies
Jongwan Ko, Myungshin Im, Hyung Mok Lee +12
We present the mid-infrared (MIR) properties of galaxies within a supercluster in the North Ecliptic Pole region at z?0.087 observed with the AKARI satellite. We use data from the…
A tale of two GRB-SNe at a common redshift of z = 0.54
Z. Cano, D. Bersier, C. Guidorzi +71
We present ground-based and HST optical observations of the optical transients (OTs) of long-duration Gamma Ray Bursts (GRBs) 060729 and 090618, both at a redshift of z = 0.54. For…
