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 13, 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...
