Diversity of Ionized Gas Structures in Nearby Metal-poor Dwarf Galaxies
Yuki Takagishi, Takuya Hashimoto, Kazuya Matsubayashi +13
We investigate whether optical and far-infrared [O III] emission from nearby metal-poor dwarf galaxies can be represented by a homogeneous one-zone ionized-gas model with a single…
RIOJA. Environmental Effects on Stellar Populations and Ionized Gas in a Protocluster at
Wataru Osone, Takuya Hashimoto, Javier Álvarez-Márquez +23
Protoclusters in the epoch of reionization provide key laboratories for investigating how environment shapes early galaxy formation and evolution, and may also have contributed to…

We present analysis of JWST NIRCam and NIRSpec observations of the galaxy SXDF-NB1006-2 at , as part of the Reionization and the ISM/Stellar Origins with JWST and ALMA (…
Early massive galaxy formation in the core of a galaxy protocluster 650 million years after the Big Bang
Yoshinobu Fudamoto, Yurina Nakazato, Daniel Ceverino +24
Rest-frame optical observations with the James Webb Space Telescope (JWST) have uncovered a population of massive galaxies, exceeding solar masses, present less than a bi…
Early galaxy evolution: The complex interstellar medium distribution of the z~7 galaxy A1689-zD1

RIOJA. A Clumpy Galaxy Assembly at Redshift 6.81 Revealed by JWST
Ken Mawatari, Luca Costantin, Mitsutaka Usui +21
Spatially resolved multi-wavelength analysis is essential to study galaxy formation and evolution. A UV-bright galaxy COS-2987030247 at is one of the Rosetta Stones in t…
Compact Ionized Gas Region Surrounded by Porous Neutral Gas in a Dusty Lyman Break Galaxy at Redshift
Masato Hagimoto, Yoichi Tamura, Akio K. Inoue +9
Porous interstellar medium (ISM) structure in galaxies at the epoch of reionization (EoR) gives us a hint to understand what types of galaxies contribute to reionization. Although…
