Halo uncertainties in electron recoil events at direct detection
  experiments
  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 $ \sim 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 recent cosmological $N$-body simulations while even larger
deviations are obtained in case of the observational uncertainties.
