Gamma-ray bursts reveal the history and faint contributors of cosmic reionization

Jing-Meng Hao, Paolo Cassata, Zhen-Ya Zheng +5

Star-forming galaxies are generally believed to be the main drivers of cosmic reionization. However, the relative contributions of bright and faint galaxies to this process remain…

The ALPINE-CRISTAL-JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z~5

Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois +54

We present the stellar mass-metallicity relation (MZR) and mass-metallicity-star formation relation ("fundamental metallicity relation"; FMR) of 18 massive (log(M/Msun) = 9.5 - 11)…

A first empirical derivation of the average dust attenuation law at 2<z<7

Giulia Rodighiero, Gaia Edes Esposito, Daniela Calzetti +10

Dust attenuation strongly affects the observed spectral energy distributions of galaxies, introducing significant uncertainties in the derivation of key physical properties such as…

Near-infrared emission line diagnostics for AGN from the local Universe to redshift 3

Antonello Calabrò, Laura Pentericci, Anna Feltre +35

Optical rest-frame spectroscopic diagnostics are usually employed to distinguish between star formation and AGN-powered emission. However, this method is biased against dusty sourc…

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…

The ALPINE-CRISTAL-JWST Survey: JWST/IFU Optical Observations for 18 Main-Sequence Galaxies at z=4-6

A. L. Faisst, S. Fujimoto, A. Tsujita +80

To fully characterize the formation and evolution of galaxies, we need to observe their stars, gas, and dust on resolved spatial scales. We present the ALPINE-CRISTAL-JWST survey,…
