Redshift distribution of the number density of Hα emitters above flux thresholds 2 × 10⁻¹⁶ erg s⁻¹ cm⁻² (top panel) and 5 × 10⁻¹⁷ erg s⁻¹ cm⁻² (bottom panel), corresponding to the respective EWS and EDS flux limits. Predictions from the GAEA-LC framework (blue lines) use the intrinsic population of emitters (solid) and dust-attenuated versions with a flat A_v (dashed) and a mass-dependent A_v scaling (dotted Garn & Best 2010). Models 1 (green), 2 (black), and 3 (red) from Pozzetti et al. (2016) represent various model fits to collections of uncorrected Hα survey results (data points, covering yellow-shaded area) across different redshift ranges. Model 3 has been fit to data points outlined in red.
