Nearby sources, such as the Galactic Center, are of promising sites for the indirect dark matter searches. Recent studies have identified an excess of TeV photons in in the central 15 parsecs of the Milky Way, incident in position with the super-massive black hole. The energy spectrum can be well described by a super-exponential template for the energy spectrum as expected from the dark matter interpretation of the excess. On the other hand the angular spectrum around the central region can help us constrain the spatial distribution of dark matter. We study the properties of the would-be dark matter signal and show that the density profile would have to be steeper than the standard cuspy profile predicted by N-body simulations.
