Description
The dark matter direct detection rates are highly correlated with the phase space distribution of
dark matter particles in our galactic neighbourhood. In this paper we make a systematic study of the
impact of astrophysical uncertainties on electron recoil events at the direct detection experiments
with Xenon and semiconductor detectors. We find that within the standard halo model there can
be up to ∼ 50% deviation from the fiducial choice in the exclusion bounds from these observational.
uncertainties. For non-standard halo models we report a similar deviation from the fiducial standard
halo model when fitted with state-of-art N-body simulation while even larger deviations are obtained
in case of the observational uncertainties
