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…
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…
BEACON: JWST NIRCam Pure-parallel Imaging Survey. II. Physical Properties of Galaxies
Yechi Zhang, Takahiro Morishita, Kimi C. Kreilgaard +23
We present photometric properties of 161 galaxy candidates at selected from the second data release (DR2) of BEACON, a JWST Cycle 2 pure-parallel NIRCam imaging program. C…
BEACON: JWST NIRCam Pure-parallel Imaging Survey. I. Survey Design and Initial Results
Takahiro Morishita, Charlotte A. Mason, Kimi C. Kreilgaard +32
We introduce the Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON) survey, a JWST Cycle2 program allocated up to 600 pure-parallel hours of observations. BEA…
