Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.

Galaxies at z~7-10 display diverse metallicity gradients often flattened by tidal interactions or feedback, and sit well below the local fundamental metallicity relation due to pristine gas accretion.
Luminous Lyα emitters at z≈6 are low-mass ultra-young dwarf starbursts with median Lyα escape fractions above 40 percent, driven by vigorous star formation and low dust content.

A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at $z\sim6-8$
Direct [OIII]4364-based metallicities show that galaxies with stellar masses 10^6.7-9 solar masses at z~6-8 are 0.3-0.5 dex more metal-poor than local galaxies of the same mass, with slope 0.25 and 0.2 dex scatter.

An Updated Characterization of Luminous Ly{\alpha} emitters at the End of Reionization
Luminous Lyα emitters at z≈6 are low-mass ultra-young dwarf starbursts with median Lyα escape fractions above 40 percent, driven by vigorous star formation and low dust content.
