arxiv.org/abs/2601.20045 GLIMPSE-DDT spectroscopic properties of faint-end galaxies at $z\sim6$: Towards first metal enrichment, dust production, and ionizing photon production
JWST/NIRSpec spectra from the GLIMPSE survey's Abell S1063 lensing field cover sixteen galaxies fainter than M_UV = -17 near redshift six. Strong [OIII] emission extends the mass-metallicity relation down to about a million solar masses, suggesting two separate paths to early metal enrichment.
