DM fraction of ensemble averages. Upper panel: dark matter fraction within R_out as a function of stellar mass (). The brown hexagons with error bars shielded by big light-peach hexagons represent our averaged data, and the blue shaded area shows the 1, 2, and 3σ error at DM fraction. For comparison, we show the local star-forming disk galaxies (Persic et al. 1996) represented by the blue stars (in both panels), where the size of the marker represents the uncertainty in the values. The red hexagon represents the z ∼ 1 SFGs (Tiley et al. 2019b). Lower panel: vs. , color coded by stellar mass. The gray shaded area represents the theoretically not allowed region (i.e., . The blue shaded area shows the maximum scatter in the relation. The lower panel interior of blue stars are color coded by stellar mass.
