We introduce serra, a suite of zoom-in high-resolution (, at z= 7.7) cosmological simulations
including non-equilibrium chemistry and on-the-fly radiative transfer. The outputs are post …

We report 18 dust continuum detections (≥ 3.3 σ) at∼ 88 and 158 out of 49 ultraviolet (UV)-
bright galaxies (M UV<− 21.3 mag) at> 6.5, observed by the Cycle-7 Atacama Large …

ABSTRACT The recent James Webb Space Telescope tentative discovery of a population of
super-early (redshift z> 10), relatively massive (stellar mass M*= 108–109M⊙) and evolved …

Context. Galaxy mergers are thought to be one of the main mechanisms of the mass
assembly of galaxies in the Universe, but there is still little direct observational evidence of …

Recent attempts to detect [O iii] 88 m emission from super-early (z> 10) galaxy candidates
observed by JWST have been unsuccessful. Non-detections can be either due to wrong …

We study the ultraviolet (UV) continuum β slope of a sample of 166 clumps, individual star-
forming regions observed in high-redshift galaxies. They are hosted by 67 galaxies with …

High-redshift star-forming galaxies have very different morphologies compared to nearby
ones. Indeed, they are often dominated by bright star-forming structures of masses up to 108 …

Context. Going from a redshift of 6 down to nearly 4, galaxies grow rapidly from low-mass
galaxies towards the more mature types of massive galaxies seen at cosmic noon. Growth …

While the kinematics of galaxies up to z∼ 3 have been characterized in detail, only a
handful of galaxies at high redshift (z> 4) have been examined in such a way. The Atacama …

Galaxy evolution emerges from the balance between cosmic gas accretion, fueling star
formation, and supernova (SN) feedback, regulating the metal enrichment. Hence, the stellar …
