![UV absolute magnitude determined for our full sample. Left panel: M$\rm _{UV}$ plotted against spectroscopic redshift. We overlay as a black line the apparent m$\rm _{UV}=29$ mag used in the selection of the high-redshift targets, plotted as dashed ($z\gt 5.7$) and dotted ($z\lt 5.7$) lines to indicate the UV selection within our full sample. We use galaxies below this line in our redshift comparison to obtain a consistent selection across our sample. The EELG subsample are shown in blue and the non-EELGs in orange. Right panel: M$\rm _{UV}$ plotted against the [O iii]$\lambda 5007$ EW. We additionally overlay dashed lines at M$\rm _{UV}$ = −18.0 and −19.5, which correspond to the UV absolute magnitude thresholds used in Endsley et al. (2024). Galaxies in our high-redshift subsample ($z\gt 5.7$) are shown in blue, while those at lower redshifts are orange.
