Abstract

We present rest-frame optical spectra for a sample of nine low-mass star-forming galaxies in the redshift range 1.5 = 0.01 ± 0.08, suggesting a universal relationship. Remarkably, the scatter around the fundamental metallicity relation is only 0.24 dex, smaller than that observed locally at the same stellar masses, which may provide an important additional constraint for galaxy evolution models.
