Open Access

TL;DR

This paper reports the discovery and analysis of the first spectroscopically confirmed galaxies at redshifts greater than 12, revealing rapid formation, intense star formation, and their potential role in cosmic reionization.

Contribution

It presents the identification and characterization of the earliest galaxies at z>12 using JWST data, including spectroscopic confirmation and stellar population modeling.

Findings

01

Galaxies contain about a hundred million solar masses in stars.

02

Galaxies are less than one hundred million years old.

03

They exhibit elevated star formation rate surface densities.

Abstract

Surveys with James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxies may be more massive and abundant than previously thought. However, without confirmed distances, their inferred properties remain uncertain. Here we identify four galaxies located in the JWST Advanced Deep Extragalactic Survey (JADES) Near-Infrared Camera (NIRCam) imaging with photometric redshifts z~10-13. These galaxies include the first redshift z>12 systems discovered with distances spectroscopically confirmed by JWST in a companion paper. Using stellar population modelling, we find the galaxies typically contain a hundred million solar masses in stars, in stellar populations that are less than one hundred million years old. The moderate star formation rates and compact sizes suggest elevated star…
