Abstract

The Dark Matter (DM) spike induced by the adiabatic growth of a massive Black Hole (BH) in a cuspy environment, may explain the thermal DM density required to fit the cut-off in the HESSJ1745-290 γ-ray spectra (F. Aharonian et al. (2009)) as TeV DM signal with a background component (Cembranos et al. (2012)). The spike extension appears comparable with the HESS angular resolution.
