Mass distributions for the halos in our simulation and for SDSS galaxies. The solid light blue line shows the mass distribution for Legacy MGS galaxies, while the dashed light blue line is the same distribution shifted by one order of magnitude to provide a reference for the expected position of the mass distribution of the halos hosting the Legacy MGS galaxies. The red line is the mass distribution for simulated galaxies selected through a cut in mass and the green line is the mass distribution of simulated galaxies selected through a cut in magnitude. We note that the mass reported on the x-axis is the stellar mass for SDSS galaxies and the virial mass for the halos and galaxies in our simulation.
