Gas velocity dispersion σ₀ evolutionary trend and correlations. Top: velocity dispersion, σ₀, as a function of z for the PUMA sub-sample (red dots) and other individual ionised gas measurements from the literature, distinguishing between the different samples presented in Appendix D, as labelled. The Übler et al. (2019) evolutionary trend of MS galaxies is shown with a solid curve (shaded area: 1σ scatter around the average trend). Middle: σ₀ as a function of the SFR for all targets already reported in the first panel and the KMOS^3D galaxies (grey points; Übler et al. 2019). K18 models and a linear fit (with scatter) are also reported, as labelled. Bottom: σ₀ normalised to the evolutionary trend of MS galaxies as a function of δMS for all targets already reported above. A linear fit is also reported.
