Swift/XRT follow-up observations of TeV sources of the HESS Inner Galaxy survey

R. Landi, L. Bassani, A. Malizia +6

In order to provide a firm identification of the newly discovered Galactic TeV sources, a search for counterparts in a broad band from soft X-ray to soft gamma-rays is crucial as d…
