Abstract (from CDS):

Very high energy (>100GeV) gamma-ray emission has been detected for the first time from the composite supernova remnant G0.9+0.1 using the HESS instrument. The source is detected with a significance of ≃13σ, and a photon flux above 200GeV of (5.7±0.7_stat±1.2_sys)x10^–12/cm2/s, making it one of the weakest sources ever detected at TeV energies. The photon spectrum is compatible with a power law (dN/dE∝E^–Γ) with photon index Γ=2.40±0.11_stat±0.20_sys. The gamma-ray emission appears to originate in the plerionic core of the remnant, rather than the shell, and can be plausibly explained as inverse Compton scattering of relativistic electrons.
