Cosmological 3D HI Gas Map with HETDEX Ly Emitters and eBOSS QSOs at : IGM-Galaxy/QSO Connection and a 40-Mpc Scale Giant HII Bubble Candidate

Shiro Mukae, Masami Ouchi, Gary J. Hill +20

We present cosmological ( Mpc) distributions of neutral hydrogen (HI) in the inter-galactic medium (IGM) traced by Ly Emitters (LAEs) and QSOs at , selected w…

Extremely Metal-Poor Representatives Explored by the Subaru Survey (EMPRESS). I. A Successful Machine Learning Selection of Metal-Poor Galaxies and the Discovery of a Galaxy with M*<10^6 M_sun and 0.016 Z_sun

Takashi Kojima, Masami Ouchi, Michael Rauch +18

We have initiated a new survey for local extremely metal-poor galaxies (EMPGs) with Subaru/Hyper Suprime-Cam (HSC) large-area (~500 deg^2) optical images reaching a 5 sigma limit o…

SILVERRUSH. III. Deep Optical and Near-Infrared Spectroscopy for Lya and UV-Nebular Lines of Bright Lya Emitters at z=6-7

Takatoshi Shibuya, Masami Ouchi, Yuichi Harikane +23

We present Lya and UV-nebular emission line properties of bright Lya emitters (LAEs) at z=6-7 with a luminosity of log L_Lya/[erg s-1] = 43-44 identified in the 21-deg2 area of the…
