Characterizing chemical abundance ratios in extremely metal-poor star-forming galaxies in DESI EDR

I. A. Zinchenko, M. Sobolenko, J. M. Vilchez +1

We present a search for galaxies in the local Universe with extremely low oxygen abundance, that is, more than 25 times lower than solar, which corresponds to 12 + log(O/H) < 7.3.…
