VIA lecture by Justinn read "The Local Dark Matter Density" was given on friday 5 Juen 2015.
It's pdf presentation is attached and the record is in VIA library
During the lecture the following questions were put and comments made:

Arunan: 6 dimensons? what is the 5th?
Johann Cohen-Tanugi: the errors are only statistical there?
Houri Ziaeepour: Have you found any cusp or unusual clumping of DM in the disk or halo ?

Shantanu: what are your thoughts Pierre Sikivie's argurments where he has argued that dark matter in our galaxy is distributed in terms of caustics and not NFW (or similar profiles)

M.Yu.Khlopov: The first paper on the baryonic feedback in dark matter distriubution was: Astrophysical bounds on the mass of heavy stable neutral leptons. Yadernaya Fizika (1980) V. 31, PP. 1286-1294. With Ya.B.Zeldovich, A.A.Klypin and V.M.Chechetkin. [English translation: Sov.J.Nucl.Phys. (1980) V.31, PP. 664-669]. It's scan is attached to this post.

Stacy McGaugh: I am finding a heavy-ish MW disk, consistent with spherical DM equivalent 0.009Msun/pc^3. But I also see evidence for bumps and wiggles in both the surface density of stars and the rotation curve. dV/dR bounces around so that Oort's A and B vary on <~300 pc scales. Is this going to be another systematic headache by adding more cross terms we can't ignore?
