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…

RIOJA. The dusty outflows and density-complex interstellar medium in the N-enhanced lensed galaxy RXCJ2248-ID at z=6.1

A. Crespo Gómez, Y. Tamura, L. Colina +19

We present an analysis on the kinematics and physical properties of the ionized gas in the lensed galaxy RXCJ2248-ID at z=6.1 based on high-resolution JWST NIRSpec/IFU data in comb…

RIOJA. Young Starburst and Ionized Gas Outflows in a Galaxy Uncovered by JWST NIRCam and NIRSpec Observations

Yi W. Ren, Akio K. Inoue, Javier Álvarez-Márquez +21

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 (…

ELPIS: Accelerated metal and dust enrichment in a proto-cluster core at

Hideki Umehata, Yoichi Tamura, Yoshinobu Fudamoto +17

We present a study of the metal, dust, and molecular gas content in galaxies within the A2744-z7p9OD proto-cluster at z ~ 7.88. We focus on two galaxy groups, the Quintet and the C…

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…

Extremely UV-bright starbursts at the end of cosmic reionization

R. Marques-Chaves, D. Schaerer, M. Dessauges-Zavadsky +22

We present a study of 27 very UV-bright (-22.0<MUV<-24.4) sources at z~6 identified in SHELLQs survey. Stacking their rest-frame UV spectra reveals a prominent NV1240A P-Cygni, con…

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 observat…
