Dark matter fraction within R_out. The KMOS^3D, KGES, and KROSS datasets are represented in red, green, and blue colors, respectively. The binned dark matter fraction, calculated using weighted mean and root-mean-square statistics discussed in Section 4.2, is represented by off-white and white color hexagons, respectively, connected by black lines. The uncertainties on individual and binned data points represent the 68% confidence interval. 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 pink shaded area represents local star-forming disks (Persic et al. 1996). 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. These color codes are same throughout the text.
