First insights into the ISM at z > 8 with JWST : possible physical implications of a high [O  iii ] λ4363/[O  iii ] λ5007

We present a detailed analysis of the rest-frame optical emission line ratios for three spectroscopically confirmed galaxies at z > 7.5. The galaxies were identified in the James Webb Space Telescope (JWST) Early Release Observations field SMACS J0723.3 − 7327. By quantitatively comparing Balmer...
