Lyman-α velocity offset (ΔvLyα) versus MUV for GN-z11 (star) and other high-redshift galaxies, colour-coded by Lyman-α equivalent width. We overplot data of z > 6 galaxies with ground-based observations from the literature (Cuby et al. 2003; Pentericci et al. 2011, 2016, 2018; Vanzella et al. 2011; Willott et al. 2013, 2015; Maiolino et al. 2015; Oesch et al. 2015; Stark et al. 2015, 2017; Furusawa et al. 2016; Knudsen et al. 2016; Carniani et al. 2017; Laporte et al. 2017; Mainali et al. 2017; Hashimoto et al. 2019; see Endsley et al. 2022 and the Table 4 therein) in circles, and Lyα emitting galaxies at z ∼ 7 − 9 from CEERS NIRSpec observations (Tang et al. 2023) in squares. The prediction of the correlation between the Lyα velocity offset and MUV at z = 7 from Mason et al. (2018b) is shown by the dashed grey line. GN-z11 has properties similar to the Lyα-emitting galaxies at z ∼ 7 − 9.
