  The gamma-ray fluxes observed by the High Energy Stereoscopic System (HESS)
from the J1745-290 Galactic Center source is well fitted by the secondary
photons coming from Dark Matter (DM) annihilation in particle-antiparticle
standard model pairs over a diffuse power-law background. The spectral features
of the signal are consistent with different channels: light quarks,
electro-weak gauge bosons and top-antitop production. 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 large enhancements in the signal over DM alone simulations. The fits
return a heavy WIMP, with a mass above 10 TeV, but well below the unitarity
limit for thermal relic annihilation. The fitted background spectral index is
compatible with the Fermi-Large Area Telescope (LAT) data from the same region.
This possibility can be potentially tested with the observations of other high
energy cosmic rays.
