By comparing a collisionless cosmological N-body simulation (DM) to a smoothed particle hydrodynamics simulation (SPH) with the same initial conditions, we investigate the correspondence between dark ...

In models of dark matter with Sommerfeld-enhanced annihilation, where the annihilation rate scales as the inverse velocity, models of local substructure motivated by N-body dark matter simulations imp...
