ALMA observations of pre-JWST z ~ 10 galaxy candidates: A CO(J = 9-8) line from a ULIRG at z = 2.54 and revisit of the photometric redshifts with JWST photometry

Suzuka Arai, Yuma Sugahara, Akio K. Inoue +15

We present Atacama Large Millimetre/submillimetre Array (ALMA) observations targeting the [OIII]m line for six galaxy candidates selected with the Hubble Space Tel…

A Type Ia Supernova Candidate at : A Transient Interloper in the Search for Galaxies

Seiji Toshikage, Takahiro Morishita, Masaomi Tanaka +9

The James Webb Space Telescope (JWST) is opening a new window into the distant Universe by discovering galaxies and transients in the early Universe. We investigate a high-redshift…

A Compact Proto-group at : A Massive Galaxy Caught in Formation

Ronaldo Laishram, Yusei Koyama, Fengwu Sun +11

The authors report the discovery of a compact galaxy proto‑group at redshift ~5, confirming six members spectroscopically and measuring their stellar masses, star‑formation propert…

Assessing Ultra-Cool Dwarf Contamination in Photometrically Selected High-Redshift Galaxy Samples

Onnalin Innala, Nicha Leethochawalit, Takahiro Morishita +1

Ultra-cool dwarf stars (UCDs) are a common source of contamination in high-redshift galaxy searches as both sources are red and these early-forming galaxies can have sizes that are…

BEACON: JWST NIRCam Pure-parallel Imaging Survey. IV. A Systematic Search for Galaxy Overdensities and Evidence for Gas Accretion Mode Transition

Ryo Albert Sutanto, Takahiro Morishita, Tadayuki Kodama +20

We systematically search for galaxy overdensities using 20 independent fields with a minimum of six filters (F090W, F115W, F150W, F277W, F356W, and F444W) from BEACON, the JWST Cyc…

A stellar dynamical mass measurement of an inactive black hole at redshift 2

Andrew B. Newman, Meng Gu, Sirio Belli +34

Supermassive black holes and their host galaxies grow together over time, producing correlations between the black hole mass and various galaxy properties. Determining the evolutio…
