Dissecting the Interstellar Media of a Wolf–Rayet Galaxy at z = 2.76

We report JWST/NIRSpec observations of a star-forming galaxy at z = 2.76, MACS J1149-WR1. We securely detect two temperature-sensitive auroral lines, [S iii ] 6312 (7.4 σ ) and [O ii ] 7320+7331 doublets (10 σ ), and tentatively [ n ii ] 5755 (2.3 σ ) for the first time in an individual galaxy at z...
