Abstract (from CDS):

We report the detection of a point-like source of very high energy (VHE) γ-rays coincident within 1' of Sgr A*, obtained with the HESS array of Cherenkov telescopes. The γ-rays exhibit a power-law energy spectrum with a spectral index of -2.2±0.09±0.15 and a flux above the 165GeV threshold of (1.82±0.22)x10–7/m2/s. The measured flux and spectrum differ substantially from recent results reported in particular by the CANGAROO collaboration. gamma-rays: observations - Galaxy: centre
