Bursty star formation, chemical enrichment, and star cluster formation in numerical analogues of GN-z11
Takayuki R. Saitoh, Yutaka Hirai, Michiko S. Fujii +1
The James Webb Space Telescope reveals anomalous nitrogen enrichment (high N/O ratios) in compact, star-forming galaxies, such as GN-z11 at . The origin of this chemical s…
