Dark Matter implications of the Fermi-LAT measurement of anisotropies in
  the diffuse gamma-ray background: status report
  For the first time, the Fermi-LAT measured the angular power spectrum (APS)
of anisotropies in the diffuse gamma-ray background. The data is found to be
broadly compatible with a model with contributions from the point sources in
the 1-year catalog, the galactic diffuse background, and the extragalactic
isotropic emission; however deviations are present at both large and small
angular scales. In this study, we complement the model with a contribution from
Dark Matter (DM) whose distribution is modeled exploiting the results of the
most recent N-body simulations, considering the contribution of extragalactic
halos and subhalos (from Millennium-II) and of galactic substructures (from
Aquarius). With the use of the Fermi Science Tools, these simulations serve as
templates to produce mock gamma-ray count maps for DM gamma-ray emission, both
in the case of an annihilating and a decaying DM candidate. The APS will then
be computed and compared with the Fermi-LAT results to derive constraints on
the DM particle physics properties. The possible systematic due to an imperfect
model of the galactic foreground is also studied and taken into account
properly. The present paper reports on the status of the project.
