HESS upper limit on the very high energy gammay-ray emission from the globular cluster 47 Tucanae (Research Note)
(EDP sciences, 2009)
Observations of the globular cluster 47 Tucanae (NGC 104), which contains at least 23 ms pulsars, were performed with the HESS telescope
system. The observations lead to an upper limit of F(E > 800 GeV) < 6.7 × 10−13 cm−2 ...
Discovery of gamma-ray emission from the shell-type supernova remnant RCW 86 with HESS
(IOP Publishing, 2009)
The shell-type supernova remnant (SNR) RCW 86, possibly associated with the historical supernova SN 185, with its relatively large size (about 40' in diameter) and the presence of nonthermal X-rays is a promising target ...
