Redshift evolution of V_rot/σ in SERRA. The three stellar mass bins are distinguished by the line width; blue (red) markers represent σ from [C II] (Hα) synthetic observations. For comparison, predictions from TNG50 simulations (Pillepich et al. 2019) are shown with filled orange markers for z < 5. The gray triangles denote observational data points with [C II] line kinematics, including high-z DCDs (Rizzo et al. 2021; Lelli et al. 2021; Fraternali et al. 2021; Tsukui & Iguchi 2021; Roman-Oliveira et al. 2023; Pope et al. 2023; Rowland et al., in prep.), ALPINE disk galaxies (Jones et al. 2021), archival 4 < z < 7.7 [C II] data (Parlanti et al. 2023), the first discovered EoR disk galaxies (Smit et al. 2018), and the turbulent HZ4 system at z = 5.5 (Herrera-Camus et al. 2022). The gray squares represent data with nebular Hα and [OIII] kinematics (de Graaff et al. 2024; Parlanti et al. 2024). The filled (empty) markers distinguish spatially (barely) resolved observations.
