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…
The NIRISS PASSAGE Spectroscopic Redshift Catalog in COSMOS
Mason S. Huberty, Kalina V. Nedkova, Zahra Sattari +34
We present the Parallel Application of Slitless Spectroscopy to Analyze Galaxy Evolution (PASSAGE) spectroscopic redshift catalog in the COSMOS field. PASSAGE is a JWST Cycle 1 Nea…
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 BoRG- Survey: Analogs at to the UV-luminous Galaxy Population at
SofÃa Rojas-Ruiz, Guido Roberts-Borsani, Takahiro Morishita +7
The population of bright galaxies at discovered by JWST, including the so-called "blue monsters", has been difficult to reconcile with standard galaxy evolution models…
A Portrait of the Cosmic Reionisation History in the Context of the Early Dark Energy Model
Weiyang Liu, Xin Wang, Hu Zhan +3
Recent JWST observations of Lyman- emission at indicate a rapid reionization of the intergalactic medium within the first Myr. The required Lyman contin…
