An emerging baryon cycle in a galaxy 500 million years after the Big Bang

Shengzhe Wang, Xin Wang, Hang Zhou +17

The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…

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…

Spatially resolved gas-phase metallicity at z~2-3 with JWST/NIRISS

Ayan Acharyya, Peter J. Watson, Benedetta Vulcani +24

Spatially resolved gas-phase metallicity maps are a crucial element in understanding the chemical evolution of galaxies. We present spatially resolved metallicity maps obtained fro…

BEACON: JWST NIRCam Pure-parallel Imaging Survey. III. Constraints on the UV LF and the Clustering of z~7-14 Galaxies

Kimi C. Kreilgaard, Charlotte A. Mason, Takahiro Morishita +22

The James Webb Space Telescope (JWST) has extended the frontier of galaxy detection to redshifts z>11, finding a high abundance of UV-bright sources that challenge theoretical mode…

The GLASS-JWST Early Release Science Program. V. H luminosity functions at and

Yuxuan Pang, Xin Wang, Tommaso Treu +11

We present H luminosity function (LF) measurements at redshifts and using JWST NIRISS grism data from the GLASS-JWST survey. Based on emission lines spect…
