New stack-based strong-line calibrations from ~1500 spectra yield mass-metallicity relations at z=1-10 with decreasing metallicity toward higher redshift and no slope change, plus 50 EMPG candidates at 1-4% solar metallicity showing large scatter and opposite sSFR trends.

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.
Combining [O II] doublet data with MUSE spectra creates a homogeneous H II region catalog and compares strong-line metallicity calibrations, showing low scatter in radial gradients and [S III]/[S II] as a robust ionization parameter tracer.
A homogeneous analysis of 699 spectra yields Te-Te relations for ions including N II, O II, O III, S II, S III and Ar III, with lower dispersions for relations involving Te([N II]).
