Dark matter origin of the gamma ray emission from the galactic center
  observed by HESS
  We show that the gamma ray spectrum observed with the HESS array of Cherenkov
telescopes coming from the Galactic Center (GC) region and identified with the
source HESS J1745-290, is well fitted by the secondary photons coming from dark
matter (DM) annihilation over a diffuse power-law background. The amount of
photons and morphology of the signal localized within a region of few parsecs,
require compressed DM profiles as those resulting from baryonic contraction,
which offer $\sim 10^3$ enhancements in the signal over DM alone simulations.
The fitted background from HESS data is consistent with recent Fermi-LAT
observations of the same region.
