ABSTRACT:

The interpretation of data from direct dark matter detection experiments is subject to significant astrophysical uncertainties due to the poorly known local dark matter distribution. I will discuss the local dark matter density and velocity distribution of Milky Way-like galaxies obtained from the high resolution EAGLE and APOSTLE hydrodynamic simulations. To make reliable predictions for direct detection searches, we identify simulated haloes which satisfy the Milky Way observational constraints. Using the dark matter distribution obtained for the selected Milky Way-like analogues, I will present an analysis of current direct detection data, and show how the the allowed regions and exclusion limits set by direct detection experiments in the dark matter mass and spin-independent cross section plane shift with respect to the Standard Halo Model.
