Discovery of very high energy gamma-ray emission coincident with molecular clouds in the W28 (G6.4-0.1) field

HESS Collaboration, F Aharonian

We observed the W28 field (for ~40 h) at Very High Energy (VHE) gamma-ray energies (E>0.1 TeV) with the H.E.S.S. Cherenkov telescopes. A reanalysis of EGRET E>100 MeV data was also…
