Dark Matter Substructure and Dwarf Galactic Satellites

Figure 11

The cumulative luminosity function of subhalos in the three MW-sized halos shown in Figure 10 with the simple luminosity assignment ansatz of (4). The luminosity function includes all subhalos within 417 kpc from the center of each halo, the same radius as was used to construct the luminosity function of the observed satellites shown in Figure 6. The points with (Poisson) error bars, connected by the dashed line, and the shaded region show the observed and inferred satellite luminosity functions within the same radius for classical and ultra-faint dwarfs, respectively, as compiled by [56] (see text for details).
