Abstract (from CDS):

We report the detection of TeV γ-rays from the shell-type supernova remnant RX J0852.0-4622 with data of 3.2h of live time recorded with HESS in February 2004. An excess of (700±60) events from the whole remnant with a significance of 12σ was found. The observed emission region is clearly extended with a radius of the order of 1° and the spatial distribution of the signal correlates with X-ray observations. The spectrum in the energy range between 500GeV and 15TeV is well described by a power law with a photon index of Γ=2.1±0.1_stat±0.2_syst and a differential flux at 1TeV of φ_1TeV=(2.1±0.2_stat±0.6_syst)x10^–11/cm²/s/TeV. The integral flux above 1TeV was measured to be Φ(E>1TeV)=(1.9±0.3_stat±0.6_syst)x10^–11/cm²/s, which is at the level of the flux of the Crab nebula at these energies. More data are needed to draw firm conclusions on the magnetic field in the remnant and the type of the particle population creating the TeV γ-rays.
