Discovery of extended VHE gamma-ray emission from the vicinity of the young massive stellar cluster Westerlund 1

Abstract

Results obtained in very-high-energy (VHE; E }= 100 GeV) gamma-ray observations performed with the H.E.S.S. telescope array are used to investigate particle acceleration processes in the vicinity of the young massive stellar cluster Westerlund 1 (Wd 1).
