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. 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…
Precision near-IR spectroscopy for understanding AGN physics and shed light on the H0 tension -- SHARP Science Book
M. Signorini, V. N. Bennert, E. Dalla Bontà +3
The persistent tension between early- and late-Universe measurements of the Hubble constant (H0) remains on of the most significant challenges in modern cosmology. The Spectroastro…
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…
JWST Spectroscopic Insights Into the Diversity of Galaxies in the First 500 Myr: Short-Lived Snapshots Along a Common Evolutionary Pathway
Guido Roberts-Borsani, Pascal Oesch, Richard Ellis +21
We investigate the nature and spectroscopic diversity of early galaxies from a sample of 41 sources at z>10 with JWST/NIRSpec prism observations. We compare the properties of stron…
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…
