V_max/σ_gas as a function of redshift and stellar mass. Squares represent the results from KMOS^3D (Wisnioski et al. 2019). Circles show the V_max/σ_gas for the whole z > 4 sample including the results of this work. Solid lines show the results obtained by TNG50 simulations (Pillepich et al. 2019). Dashed lines show the results obtained by SERRA simulations (Kohandel et. al. in prep.). Different stellar mass bins are represented with different colors.
