Nitrogen enhancements 440 Myr after the big bang: supersolar N/O, a tidal disruption event, or a dense stellar cluster in GN-z11?
Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon,
nitrogen, and helium emission lines at z= 10.6. Using the measured line fluxes, we derive …
