              *The dark matter distribution of the Milky Way*


The presence of dark matter on a wide range of astrophysical scales is one
of the observational pillars of the current cosmological model. In
particular, spiral galaxies are known to be dark matter dominated systems,
and one of the most outstanding astrophysical proofs of its existence.

Yet, retrieving information about the the dark matter distribution in our
very own spiral Galaxy, the Milky Way, is quite challenging. I will first
show how a new set of analysis of purely observational data permit to draw
strong model-independent conclusions on the presence of DM  in the Milky
Way and especially in its innermost regions.

Then, how these very sets of data allow us to both sketch the DM
distribution while getting rid of theoretical bias, and to refine analysis
based on theoretical priors (i.e. profiles  from numerical simulations such
as NFW or Einasto) to an unprecedented level of precision.

These new results offer a solid up-to-date quantitative estimate of
astrophysical uncertainties in the search for Dark Matter, and open up an
interesting avenue for the study of the dark matter distribution in the
Milky Way with forthcoming observational results.
