Supermassive Stars May Spark High Nitrogen in GN-z11 (Z=10.6)
Unraveling a Nitrogen Anomaly in the Early Universe Astronomers recently grapple with a surprising find: GN-z11, one of the most distant and ancient galaxies observed, shows unusually high levels of nitrogen for its age and developmental stage. Located at a redshift of z = 10.6, the galaxy formed when the universe was less than 500…

Supermassive Stars Explain Nitrogen Boost in GN-z11
Introduction: A Nitrogen Enigma in the Early Universe Astronomers have long suspected that the first galaxies formed with simple chemical footprints. Yet recent observations of GN-z11, a galaxy seen as it was when the universe was just about 420 million years old, reveal unusually high nitrogen levels. This surprising finding challenges conventional models of early…
