Dark matter fraction within R_opt. The KMOS^3D, KGES, and KROSS datasets are represented in red, green, and blue colors, respectively. For comparison, we include two local massive disk galaxies: the Milky Way (MW) and Andromeda (M31), represented by the blue and the orange star, respectively. The solid black dashed line represents the 100% dark matter regime, while the yellow dashed line represents the baryon-dominated regime. The gray shaded area indicates the forbidden region, where galaxies with M_dyn < M_bar are located.
