Evolution of the ratio between the rotational velocity and the velocity dispersion with redshift. Red and blue small symbols represent the value of V/σ for each ring (see also Fig. 11) for Hα and [C II], respectively. While large symbols are the mean V/σ value across the galaxy with the two tracers. Gray symbols are other literature results, in particular, circles represent the results from kinematic studies that exploited ionized gas tracers (i.e., Hα, [O III]; Green et al. 2014; Turner et al. 2017; Förster Schreiber et al. 2018; Wisnioski et al. 2019; Parlanti et al. 2023; de Graaff et al. 2024), while triangles represent the V/σ values for galaxies studied though the molecular or neutral emission lines (i.e., [C II], CO; Rizzo et al. 2020, 2021, 2023; Fraternali et al. 2021; Jones et al. 2021; Girard et al. 2021; Lelli et al. 2021; Tsukui & Iguchi 2021). The dashed line is the demarcation between rotational supported (upper) and dispersion supported (lower).
