Examples of mass modeled rotation curves in the case of the maximum stellar disk scenario (upper panel) and maximum stellar+gas disk (lower panel). The best-fit parameters are shown in the right column, and color codes are given in the legend of the plot, where ‘MM’ indicates dynamical mass-model profiles estimated using Bayesian inference and ‘fid’ stands for the fiducial profile derived from a given photometric mass. This example demonstrates that (1) the model is incapable of fitting the observations using only baryons, and (2) the best-fit values for stellar or gas mass are an order of magnitude higher than their fiducial values, which is unrealistic given the uncertainties in the observations. Therefore, we suggest that the dark matter halo component is required in high-z galaxies.
