An Attenuation Bump at z=9.3: Probing Dust Diversity at Cosmic Dawn

Giulia Rodighiero, Santiago Álvarez-Córdoba, Michele Catone +46

We report the identification of a UV attenuation bump in the Black Pearl, a galaxy at a spectroscopic redshift of 9.3335 observed with JWST/NIRSpec as part of the ZENITH and EMBER…

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…

Early results from GLASS-JWST. XXVII. The mass-metallicity relation in lensed field galaxies at cosmic noon with NIRISS

Xianlong He, Xin Wang, Tucker Jones +20

We present a measurement of the mass-metallicity relation (MZR) at cosmic noon, using the JWST near-infrared wide-field slitless spectroscopy obtained by the GLASS-JWST Early Relea…
