Balmer Break Galaxy Candidates at : a Potential View on the Star-Formation Activity at
Ken Mawatari, Akio K. Inoue, Takuya Hashimoto +15
We search for galaxies with a strong Balmer break (Balmer Break Galaxies; BBGs) at over a 0.41 deg effective area in the COSMOS field. Based on rich imaging data, in…
Large Population of ALMA Galaxies at z>6 with Very High [OIII]88um to [CII]158um Flux Ratios: Evidence of Extremely High Ionization Parameter or PDR Deficit?
Yuichi Harikane, Masami Ouchi, Akio K. Inoue +20
We present our new ALMA observations targeting [OIII]88um, [CII]158um, [NII]122um, and dust continuum emission for three Lyman break galaxies at z=6.0293-6.2037 identified in the S…
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…
3D Distribution Map of HI Gas and Galaxies Around an Enormous Ly Nebula and Three QSOs at Revealed by the HI Tomographic Mapping Technique
Shiro Mukae, Masami Ouchi, Zheng Cai +21
We present an IGM HI tomography map in a survey volume of (cMpc) centered at MAMMOTH-1 nebula and three neighbouring…
A Giant Green Pea Identified in the Spectroscopy of Spatially Extended [OIII] Sources
Suraphong Yuma, Masami Ouchi, Seiji Fujimoto +2
We present the results of the deep Subaru/FOCAS and Keck/MOSFIRE spectroscopy for four spatially extended [O III]4959,5007 sources, dubbed [O III] blobs, at that ar…
Fast Outflows Identified in Early Star-Forming Galaxies at
Yuma Sugahara, Masami Ouchi, Yuichi Harikane +3
We present velocities of galactic outflows in seven star-forming galaxies at 5-6 with stellar masses of . Although it is challenging to observa…
