DM fraction as a function of the radius in various velocity bins of observed and simulated galaxies. The central value of f_DM(< R) is shown by solid lines in each case. The color code is the same in all panels and is as follows: EAGLE (blue), TNG100 (orange), TNG50 (green), observations in the case of the Burkert halo (black), and NFW halo (brown). In the simulations, the 1σ error in each measurement is represented by a shaded area; whereas in the observations, it is a dashed line following the same color code. The gray shaded area in each panel represents the unresolved region in the observations. The horizontal red dotted-dashed line in each panel shows the 51% DM fraction. The central value of the circular velocity of each bin is printed at the top of each panel, where and specify the simulations and observations, respectively.
