Lyα EW versus sSFR for 20 galaxies at z ≳ 7. The data points are taken from the following samples: Tang et al. (2023, blue squares), Endsley et al. (2022, red circles), Stark et al. (2017, pink hexagons). The gray points in each sample show non-detections. Also shown is GN-z11 (Bunker et al. 2023, green star). The EW of CEERS-44 has been multiplied by 0.1 for display purposes. The cyan band shows the sub-Eddington regime in which sSFR < 25 Gyr⁻¹ (no outflows expected). The two exceptions (CEERS-498 and COS-zs7-1) to our outflow condition are individually marked and discussed in the text.
