Simulations show that 10-30% pollution from supermassive star ejecta reproduces the nitrogen-enhanced abundance pattern of GN-z11 and some other high-z galaxies.

JWST auroral-line selected galaxies at high redshift show an MZR slope of 0.38 with selection biases favoring high-SFR low-metallicity systems, while stacked non-detections lie closer to the fundamental metallicity relation.
N/O ratios in z~3 star-forming galaxies are indistinguishable from low-redshift values over the metallicity range 12+log(O/H)=7.5-8.44.
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.
