Detection of the [O I] 63 m emission line from the quasar J2054-0005

Nozomi Ishii, Takuya Hashimoto, Carl Ferkinhoff +23

We report the highest-redshift detection of [O I] 63 m from a luminous quasar, J2054-0005, at based on the Atacama Large Millimeter/sub-millimeter Array Band 9 observa…

EMPRESS. X. Spatially resolved mass-metallicity relation in extremely metal-poor galaxies: evidence of episodic star-formation fueled by a metal-poor gas infall

Kimihiko Nakajima, Masami Ouchi, Yuki Isobe +47

Using the Subaru/FOCAS IFU capability, we examine the spatially resolved relationships between gas-phase metallicity, stellar mass, and star-formation rate surface densities (Sigma…

JWST/NIRSpec spectroscopy of intermediate-mass quiescent galaxies at

Riku A. Sato, Akio K. Inoue, Yuichi Harikane +9

We present the analysis of three intermediate-mass quiescent galaxies (QGs) with stellar masses of at redshifts using NIRSpec low-resolutio…

FINER: Far-Infrared Nebular Emission Receiver for the Large Millimeter Telescope

Yoichi Tamura, Takeshi Sakai, Ryohei Kawabe +34

Unveiling the emergence and prevalence of massive/bright galaxies during the epoch of reionization and beyond, within the first 600 million years of the Universe, stands as a pivot…
