The ALPINE-CRISTAL-JWST Survey: Gas-phase abundance gradients of main sequence star-forming galaxies and their kinematics at $4<z<6$

Abstract

We present gas-phase radial metallicity profiles for 20 main-sequence galaxies at $4<z<6$, primarily based on JWST NIRSpec IFU observations obtained as part of the JWST-ALPINE-CRISTAL programme. Our study aims to connect the metallicity gradients of these galaxies with their kinematic properties from [CII]158$\mu$m ALMA observations. We mapped the radial profiles of oxygen abundance using the strong-line method leveraging the rich set of rest-frame optical emission lines. Linear fits to the annular-binned radial profiles show that, on average, the metallicity gradients are slightly positive with a median of $+0.039\pm 0.010\mathrm{dexkp}{\mathrm{c}}^{-1}$. There are no substantial systematic offsets in gradients when using different line diagnostics. However, only three galaxies show a gradient $>0.05\mathrm{dexkp}{\mathrm{c}}^{-1}$ at $1\sigma$, and none have a significant negative gradient. We investigated the correlation between the metallicity gradients and the intrinsic gas velocity dispersion ${\sigma }_0$ as well as the $V_{\mathrm{rot}}/{\sigma }_0$ ratio of the disks. Combining our sample with mass-matched literature samples at $3<z<7$, we found a negative shallow correlation between $V_{\mathrm{rot}}/{\sigma }_0$ and the metallicity gradients, but no strong relationships with ${\sigma }_0$. As $V_{\mathrm{rot}}/{\sigma }_0$ increases towards later cosmic times, the observed negative trend with $V_{\mathrm{rot}}/{\sigma }_0$ is consistent with the overall cosmic evolution of metallicity gradients from high to low redshifts. This suggests that disk maturity plays a crucial role in shaping the radial metallicity gradients. [Abridged abstract]
