Comparison of Lyα Luminosity vs. M_UV for the C-LAEs in TNG300 and TNG100 at redshifts z = 2, 3, and 4 (from top to bottom). We compare our results with the observations from the Sobral et al. (2018b) SC4K LAE catalog in green. The redshift bins compared to each redshift follow those in Sobral et al. (2018b) as z = 2.22±0.02 compared to z = 2 in TNG300 (top), z = 3.1±0.4 (middle), and z = 3.9±0.3 (bottom). The lines in each row compare the median LAEs at each luminosity (solid blue line for TNG300, dashed blue line for TNG100) to the observed SC4K LAE (green lines with cross hatch).
