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.

Bursty stellar feedback produces systematically flatter metallicity gradients than smooth feedback in high-redshift galaxies across multiple simulation suites.
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.
Recalibration of the Hα surface brightness-radius relation with Gaia DR3 parallaxes yields new distances for 1130 planetary nebulae and shows breaks in the Milky Way oxygen radial gradient near the solar radius.
