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…
NOEMA3D: extended CO, [C I] and dust in massive star-forming main sequence galaxies at cosmic noon
Jianhang Chen, Linda J. Tacconi, Reinhard Genzel +34
We present a spatially resolved study of cold molecular gas and dust in ten main-sequence galaxies at z=1.1-1.6, using observations of CO(4-3), CO(3-2), [C I](1-0), and dust contin…
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…
Ram-pressure stripping caught in action in a young cluster at
Ke Xu, Tao Wang, Emanuele Daddi +16
Galaxy clusters in the local Universe are dominated by massive quiescent galaxies with old ages, formed at high redshifts. Whether their quenching is driven by internal processes o…
Spider-Webb: enhanced star formation in low-mass galaxies within the Spiderweb protocluster revealed by JWST Pa narrow-band imaging
Kazuki Daikuhara, Tadayuki Kodama, Yusei Koyama +10
Understanding the role of the environment in galaxy evolution is key to revealing the physical processes that regulate galaxy growth. We study the star formation activity of \pab\…
