69% of star-forming galaxies in z~2.3 protoclusters exhibit positive metallicity gradients, higher than field galaxies, associated with metal deficiency and interpreted as evidence for enhanced pristine gas inflows.

FIRE-2 simulations find metallicity gradients in EoR galaxies flatten from median -0.15 dex/kpc at z~10 to -0.1 at z~6, with positive correlations to stellar mass and gas flow proxy Δv/2σ and links to central SFR density.
