The Sunburst Arc with JWST. III. An Abundance of Direct Chemical Abundances

The Sunburst Arc with JWST. III. An Abundance of Direct Chemical Abundances

We measure the gas-phase abundances of the elements He, N, O, Ne, S, Ar, and Fe in an individual H ii region known to be leaking Lyman-continuum photons in the Sunburst Arc, a highly magnified galaxy at redshift z = 2.37. We detect the temperature-sensitive auroral lines [S ii ] λλ 4070, 4076, [O ii...
