Predictably Missing Satellites: Subhalo Abundance in Milky Way-like Halos

Understand

On small scales there have been a number of claims of discrepancies between the standard Cold Dark Matter (CDM) model and observations.

• The 'missing satellites problem' infamously describes the overabundance of subhalos from CDM simulations compared to the number of satellites observed in the Milky Way.
• A variety of solutions to this discrepancy have been proposed; however, the impact of the specific properties of the Milky Way halo relative to the typical halo of its mass have yet to be explored.
• Motivated by recent studies that identified ways in which the Milky Way is atypical (e.g., Licquia et al.
