Query: Constraining the Milky Way Dark Matter Density Profile with Gamma-Rays
  with Fermi-LAT   We study the abilities of the Fermi-LAT instrument on board of the Fermi
mission to simultaneously constrain the Milky Way dark matter density profile
and some dark matter particle properties, as annihilation cross section, mass
and branching ratio into dominant annihilation channels. A single dark matter
density profile is commonly assumed to determine the capabilities of gamma-ray
experiments to extract dark matter properties or to set limits on them.
However, our knowledge of the Milky Way halo is far from perfect, and thus in
general, the obtained results are too optimistic. Here, we study the effect
these astrophysical uncertainties would have on the determination of dark
matter particle properties and conversely, we show how gamma-ray searches could
also be used to learn about the structure of the Milky Way halo, as a
complementary tool to other type of observational data that study the
gravitational effect caused by the presence of dark matter. In addition, we
also show how these results would improve if external information on the
annihilation cross section and on the local dark matter density were included
and compare our results with the predictions from numerical simulations.
