Dark Matter Substructure and Dwarf Galactic Satellites

Figure 6

The luminosity function of dwarf galaxies around the Milky Way. The function includes all observed galaxies within 417 kpc of the Milky Way. The red circles connected by the dotted line show the luminosity function as observed, without any corrections for incompleteness. The green circles connected by the dashed line show the observed luminosity function corrected for limited area coverage of surveys on the sky. The blue circles connected by the solid line show luminosity function corrected for the radial bias using radial distribution of subhalos from the Via Lactea I simulation. Adopted from [56].
