Direct Te-based metallicities at z≈10 are 3× lower than at z=0-3, extending the gradual FMR offset and pointing to pristine gas inflows during early galaxy assembly.
New empirical calibrations between 19 emission-line ratios and oxygen abundance are derived from direct electron-temperature measurements in 139 star-forming galaxies at z=1.4-10.6.
