Discovery of the Radio and X-Ray Counterpart of TeV γ-Ray Source HESS J1731-347

We discover a faint shell-type radio and X-ray source, G353.6-0.7,associated with HESS J1731-347.G353.6-0.7 is likely an old supernova remnant (SNR), based on radio (0.8 GHz, 1.4 GHz and 5 GHz), infrared (8 µm from the GLIMPSE Legacy Project and 21 µm from the Midcourse Space Experiment), and X-ray (0.1 keV …
