Description
Astrophysical uncertainties in the distribution of dark matter in the Milky Way complicate the interpretation of dark matter direct and indirect data, and prevent a precise determination of the properties of the dark matter particle. 
Realistic cosmological simulations of galaxy formation including baryons have recently become possible, and provide 
important information on the properties of the dark matter halo. I will discuss the dark matter density and velocity 
distribution of Milky Way-like galaxies extracted from high resolution hydrodynamic simulations. To make reliable 
predictions for direct and indirect detection searches, we identify simulated galaxies which satisfy the Milky Way 
observational constraints. Using the dark matter distribution obtained from the selected Milky Way-like galaxies, 
I will present an analysis of direct detection data, discuss the possibility of dark disks, and the implications 
for the dark matter interpretation of the Fermi GeV excess.
