Halo mass function (left panels) and stellar mass function (right panels) for the stellar mass, r-band, blue, and red samples. Each column corresponds to a different sample, while the rows represent the results at different redshifts. The colored lines show the mass functions for samples with distinct number densities. The black lines in the left panels display the halo mass function for M_h > 10¹⁰ h⁻¹ M_⊙ halos, while the purple lines in the right panels depict the stellar mass function M_★ > 10⁹ h⁻¹ M_⊙ galaxies.
