Abstract

Very high energy (>100 GeV) gamma-ray emission has been detected for the first time from the composite supernova remnant G 0.9+0.1 using the HESS instrument. The source is detected with a significance of ≈13σ, and a photon flux above 200 GeV of (5.7 ± 0.7 _stat ± 1.2 _sys) × 10 ^-12 cm ^-2 s ^-1, 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.

N2 - Very high energy (>100 GeV) gamma-ray emission has been detected for the first time from the composite supernova remnant G 0.9+0.1 using the HESS instrument. The source is detected with a significance of ≈13σ, and a photon flux above 200 GeV of (5.7 ± 0.7 stat ± 1.2 sys) × 10 -12 cm -2 s -1, 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.
