A Preview of JWST Metallicity Studies at Cosmic Noon: The First Detection of Auroral [O ii] Emission at High Redshift

We present ultradeep Keck/MOSFIRE rest-optical spectra of two star-forming galaxies at z = 2.18 in the COSMOS field with bright emission lines, representing more than 20 hr of total integration. The fidelity of these spectra enabled the detection of more than 20 unique emission lines for each galaxy...
