The Subaru high-z quasar survey: discovery of faint z~6 quasars
Nobunari Kashikawa, Yoshifumi Ishizaki, Chris J. Willott +9
We present the discovery of one or two extremely faint z~6 quasars in 6.5 deg^2 utilizing a unique capability of the wide-field imaging of the Subaru/Suprime-Cam. The quasar select…
The Redshift and Metallicity of the Host Galaxy of Dark GRB 080325 at z=1.78
Tetsuya Hashimoto, Daniel A. Perley, Kouji Ohta +5
We present near-infrared spectroscopy of the host galaxy of dark GRB 080325 using Subaru/MOIRCS. The obtained spectrum provides a clear detection of H emission and marginal [NII…
Metallicity Measurements of Gamma-Ray Burst and Supernova Explosion Sites: Lessons from HII regions in M31
Yuu Niino, Kentaro Nagamine, Bing Zhang
We examine how the small-scale (\,kpc) variation of metallicity within a galaxy, which is found in nearby galaxies, affect the observational estimates of metallicity in the expl…
A First Site of Galaxy Cluster Formation: Complete Spectroscopy of a Protocluster at
Jun Toshikawa, Nobunari Kashikawa, Roderik Overzier +8
We performed a systematic spectroscopic observation of a protocluster at in the Subaru Deep Field. We took spectroscopy for all 53 -dropout galaxies down to $z'=27.09\…
Unveiling the Origin of Fast Radio Bursts by Optical Follow Up Observations
Yuu Niino, Tomonori Totani, Jun E. Okumura
We discuss how we can detect and identify counterparts of fast radio bursts (FRBs) in future optical follow up observations of FRBs if real-time alert of FRBs becomes available. We…
