We study predictions for dark matter phase-space structure near the Sun based on highresolution simulations of six galaxy halos taken from the Aq uarius Project. The local DM density distribution is predicted to be remarkably smooth; the density at the Sun differs from the mean over a best-fit ellipsoidal equidensity contour by less than15% at the99.9% confidence level. The local velocity distribution is also very smooth, but it differs systematically from a (multivariate) Gaussian distribution… CONTINUE READING
