| For the three studied early galaxies, the reported gas metallicities were log(Zgas/Zsun) of −0.52, −0.85 and −0.78, respectively. | QUANTITATIVE | Supported | 0.8808 | 1 of 4 | 94 |
| The study reported galaxy-associated, metal-enriched gas and signatures of baryon cycling in at least a subset of luminous galaxies within the first several hundred million years of cosmic time, before the completion of reionization. | OBSERVATIONAL | Supported | 0.8581 | 1 of 4 | 107 |
| JWST/NIRSpec spectroscopy detected blueshifted absorption from neutral, low-ionization and high-ionization metal species in three galaxies at redshifts 7.2 to 9.3, with velocity offsets of approximately 50 to 250 km/s from their nebular systemic redshifts. | QUANTITATIVE | Supported | 0.8808 | 1 of 4 | 96 |
