Abstract

We investigate the predictions of the eagle and apostle hydrodynamic simulations for dark matter direct detection searches. We extract the dark matter density and velocity distribution at the Solar position for a set of simulated galaxies which satisfy Milky Way observational constraints, and use them to analyze current direct detection data. We find that the local dark matter density of the Milky Way-like galaxies fall in the range of 0.41 - 0.73 GeV/cm3, and their dark matter velocity distributions fit well a Maxwellian distribution with peak speed in the range of 223 - 289 km/s.
