An optically-dark merging system at z~6 detected by JWST
Giulia Rodighiero, Andrea Enia, Laura Bisigello +16
Near- to mid-Infrared observations (from Spitzer and JWST) have revealed a hidden population of galaxies at redshift z=3-6, called optically-dark objects, which are believed to be…
Evidence of extreme ionization conditions and low metallicity in GHZ2/GLASS-z12 from a combined analysis of NIRSpec and MIRI observations
Antonello Calabro, Marco Castellano, Jorge A. Zavala +19
GHZ2/GLASS-z12 has been recently observed by JWST with both NIRSpec and MIRI spectrographs, making it the most distant galaxy () with complete spectroscopic coverag…
A luminous and young galaxy at z=12.33 revealed by a JWST/MIRI detection of Hα and [OIII]
Jorge A. Zavala, Marco Castellano, Hollis B. Akins +37
The James Webb Space Telescope (JWST) has discovered a surprising population of bright galaxies in the very early universe (<500 Myrs after the Big Bang) that is hard to explain wi…
JWST NIRSpec Spectroscopy of the Remarkable Bright Galaxy GHZ2/GLASS-z12 at Redshift 12.34
Marco Castellano, Lorenzo Napolitano, Adriano Fontana +28
We spectroscopically confirm the mag galaxy GHZ2/GLASS-z12 to be at redshift . The source was selected via NIRCam photometry in GLASS-JWST ERS data, p…
