The gradual decline of Ly visibility in the CANDELS fields: evidence for the combined effects of galaxy evolution and reionization
L. Napolitano, L. Pentericci, A. Ferrara +35
We investigate the evolution of Ly visibility and the physical properties of Ly emitters (LAEs) across the five CANDELS fields using publicly available JWST/NIRSpec PRISM spe…
Beyond the [OIII]4363 auroral line: [NeIII]3868 as a direct tracer of electron temperature
Borja Pérez-Díaz, José M. Vílchez, Marco Castellano +9
Auroral lines enable accurate measurements of chemical abundances in ionized gaseous nebulae thanks to their sensitivity to electron temperature. However, metal-enriched systems re…
Massive Galaxies Form Early and Gray: Stellar Assembly and Dust Attenuation at from CAPERS
Katherine Chworowsky, Steven L. Finkelstein, Anthony J. Taylor +27
The stellar mass assembly of massive galaxies in the first few billion years of cosmic history remains a central challenge in galaxy formation. Galaxies with $M_\star \gtrsim 10^{1…
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…
