Median scaling relations as a function of total stellar mass illustrating the dependence on cosmological parameters. The relations for stellar half-mass radius, total-to-stellar mass ratio within the stellar half-mass radius, DM mass within the stellar half-mass radius, and total galaxy mass are shown for both uncalibrated (solid line) and calibrated (dashed line) cases. Trends were calculated using galaxies from 1024 uniform-box simulations divided into the following stellar mass intervals: log₁₀M_*/M_⊙ < 9.3, 9.3 ≤ log₁₀M_*/M_⊙ < 9.6, 9.6 ≤ log₁₀M_*/M_⊙ < 10.4, 10.4 ≤ log₁₀M_*/M_⊙ < 11.2, and log₁₀M_*/M_⊙ ≥ 11.2. Red and blue indicate trends for high and low parameter values, respectively, while the dashed gray line marks the threshold N_*, 1/2 = 50. The thresholds and median values for the parameters are provided in Table 1. Error bars represent the scatter (16th–84th percentile range), while shaded areas indicate uncertainty estimates on the median values.
