Comparison of averaged DM fraction (within R_e) of our sample with previous high-z studies. Left panel: dark matter fraction as a function of baryon surface density . The brown hexagons with error bars shielded by big light-peach hexagons represent our averaged dataset, and individual galaxies are shown by small dots, color coded by redshift. The blue shaded area represents the 1−3σ error on the DM fraction. The dashed blue line shows the relation f_DM(<​R_e) = 1−10^{−0.34 + 0.51(log Σ_Bar − 8.5)} given by Genzel et al. (2020) and their data are plotted in blue (z= 0.65−1.2) and red (z= 1.2−2.45) filled circles. Right panel: dark matter fraction as a function of stellar mass, color coded by redshift. Our dataset and its errors are presented in similar manner in both panels. Genzel et al. (2020) data are shown by filled squares. The measurements of Genzel et al. (2017), Drew et al. (2018), and Übler et al. (2018) are shown by yellow circles, a star and crosses, respectively, where the interior of each marker is color coded by redshift. The legend of the right plot is shown in the upper of left plot.
