Very high energy gamma rays from the direction of Sagittarius A*


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 165 GeV threshold of (1.82 $±$ 0.22) $times$ 10-7 m-2 s-1. The measured flux and spectrum differ substantially from recent results reported in particular by the CANGAROO collaboration.
