On the local dark matter density

In 2012, we proposed a new three-dimensional formulation, and we derived a surprisingly low dark matter density at the solar position. Bovy & Tremaine (2012) challanged this result, criticizing one of the assumptions and claiming that the data are consistent with the expectations, if a one-dimensional approach is adopted. We show here that the validity of their formulation depends on the mass distribution, and that their hypothesis is inconsistent with observations both in the Milky Way and in external galaxies. We conclude that their criticism is not a viable explanation for the lack of dark matter at the solar position detected by us.
