Left panel: Normalized distance from the void center of central galaxies in voids at z = 0 as a function of their halo mass for five redshift samples. Circle sizes decrease with increasing redshift, and the color scale represents the mean D₅ for each mass bin. Right panel: Variation in D₅ with halo mass for the same samples. The color scale indicates the mean r/R_void for each bin. The error lines were estimated via the Jackknife resampling method and using 50 subsamples.
