cds-question@unistra.frgalaxiesvisible-astronomyinfrared-astronomyspectroscopyredshiftedchemical-abundancesWe report on the gas-phase metallicity gradients of a sample of 238 star-forming galaxies at 0.6<z<2.6, measured through deep near-infrared Hubble Space Telescope slitless spectroscopy. The observations include 12 orbit depth Hubble/WFC3 G102 grism spectra taken as a part of the CANDELS Ly{alpha} Emission at Reionization (CLEAR) survey, and archival WFC3 G102+G141 grism spectra overlapping the CLEAR footprint. The majority of galaxies in this sample are consistent with having a zero or slightly positive metallicity gradient (dZ/dR>=0, i.e., increasing with radius) across the full mass range probed (8.5<logM*/M_{sun}_<10.5). We measure the intrinsic population scatter of the metallicity gradients, and show that it increases with decreasing stellar mass-consistent with previous reports in the literature, but confirmed here with a much larger sample. To understand the physical mechanisms governing this scatter, we search for correlations between the observed gradient and various stellar population properties at fixed mass. However, we find no evidence for a correlation with the galaxy properties we consider-including star formation rates, sizes, star formation rate surface densities, and star formation rates per gravitational potential energy. We use the observed weakness of these correlations to provide material constraints for predicted intrinsic correlations from theoretical models.2021ApJ...923..203Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/923/203CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/116/2805 : H II regions in spiral galaxies (Van Zee+, 1998)J/ApJ/758/135 : DEEP2 galaxies with UV spectra in the EGS (Kornei+, 2012)J/ApJS/203/24 : Structural param. of gal. in CANDELS (van der Wel+, 2012)J/ApJS/208/10 : {kappa}-distribution in HII regions (Dopita+, 2013)J/ApJ/768/74 : PHIBSS: CO obs. of star-forming galaxies (Tacconi+, 2013)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJS/225/27 : 3D-HST Survey: grism spectra master cat.
