PRISMS. U37126, a very blue, ISM-naked starburst at z=10.255 with nearly 100% Lyman continuum escape fraction
R. Marques-Chaves, J. Ãlvarez-Márquez, L. Colina +31
We present very deep (~11h) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (M_UV ~ -20), mildly lensed () galaxy at z…
The Early Maturity of High-Redshift Galaxies: Insights from sSFR, M/L and SFHs at z~7-14
P. Santini, M. Castellano, A. Calabrò +23
The James Webb Space Telescope (JWST) has revealed an unexpected excess of UV-bright galaxies at z>10, unaccounted for by extrapolations from pre-JWST observations and theoretical…
Investigating ionising sources and the complex interstellar medium of GHZ2 at
M. Castellano, L. Napolitano, B. Moreschini +27
An accurate characterisation of the physical properties of galaxies at cosmic dawn is key to understanding the origin of the high abundance of UV-bright galaxies at z10. W…
EGS-z11-R0: a red, dust-rich galaxy at Cosmic Dawn
Giulia Rodighiero, Andrea Ferrara, Michele Catone +16
Context. Galaxies discovered by JWST at z > 10 are predominantly characterized by extremely blue rest-frame UV slopes. Conversely, the existence of dust-reddened systems at such ea…
Ly visibility from z = 4.5 to 11 in the UDS field: Evidence for a high neutral hydrogen fraction and small ionized bubbles at z 7
L. Napolitano, L. Pentericci, M. Dickinson +28
The resonant scattering nature of Ly photons interacting with neutral hydrogen makes Ly emitters (LAEs) robust tracers of the intergalactic neutral hydrogen fraction, and t…
Euclid Quick Data Release (Q1): Euclid spectroscopy of quasars. 1. Identification and redshift determination of 3500 bright quasars
Euclid Collaboration, Y. Fu, R. Bouwens +354
The slitless spectroscopy mode of the NISP onboard Euclid has enabled efficient spectroscopy of objects within a large FoV. We present a large and homogeneous sample of bright quas…
