Galaxies at 4<z<6 show slightly positive gas-phase metallicity gradients on average, with a shallow negative link to how rotationally supported their disks are.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Linear fits to annular-binned radial profiles show that, on average, the metallicity gradients are slightly positive with a median of +0.039 ± 0.010 dex kpc^{-1}. ... Combining our sample with mass-matched literature samples at 3<z<7, we found a negative shallow correlation between V_rot/σ_0 and the metallicity gradients.

C2weakest assumption

The strong-line diagnostics used to convert emission-line ratios into oxygen abundances remain accurate at z>4 without significant systematic offsets from local calibrations or ionization conditions.

C3one line summary

High-redshift main-sequence galaxies exhibit slightly positive metallicity gradients (median +0.039 dex kpc^{-1}) with no significant negative cases, showing a shallow negative correlation with V_rot/σ_0 that aligns with cosmic evolution toward more mature disks.
