fluorine enrichment in young galaxies
The ramp-up of interstellar medium enrichment at z>4
Instead, we show that wolf-rayet stars are required to produce the observed fluorine abundance at this time, with other production mechanisms becoming important at later times.
These observations therefore provide an insight into the underlying processes driving the `ramp-up'phase of chemical enrichment alongside rapid stellar mass assembly in a young massive galaxy.
