Subhalo destruction in the Apostle and Auriga simulations
Subhalo destruction in the Apostle and Auriga simulations
N-body simulations make unambiguous predictions for the abundance of substructures within dark matter halos. However, the inclusion of baryons in the simulations changes the picture because processes associated with the presence of a large galaxy in the halo can destroy subhalos and substantially alter the mass function and velocity distribution …
