Velocity separation of the Lyα emission profile in relation to its luminosity for z ∼ 0 − 0.4 LAEs (Izotov et al. 2018, 2020, 2021; Izotov et al. 2022, 2024), z ∼ 0.3 GPs (Yang et al. 2017), z ∼ 2 − 3 LAEs (Kulas et al. 2012; Hashimoto et al. 2015; Vanzella et al. 2016), and z ≥ 5.5 LAEs (Hu et al. 2016; Songaila et al. 2018; Bosman et al. 2020; Meyer et al. 2021). LAE-11 is most consistent with local luminous GPs and LAEs.
