Probing the correlation between stellar and dark matter velocity distributions

Abstract content

A precise knowledge of the local dark matter velocity distribution and its uncertainties is necessary for the correct interpretation of dark matter direct detection data. High resolution hydrodynamical simulations of galaxy formation provide important information on the properties of the dark matter halo, and find that baryons generally make the local dark matter velocity distribution of Milky Way-like galaxies more Maxwellian. I will discuss the correlations between the dark matter and stellar velocity distributions of Milky Way-like galaxies extracted from state-of-the-art high resolution simulations. In particular, I will discuss if there is a subset of stars which trace the dark matter distribution in various simulated Milky Way-like galaxies.
