Discovery of a Radio Supernova Remnant and Nonthermal X-Rays Coincident with the TeV Source HESS J1813-178
We present the discovery of nonthermal radio and X-ray emission positionally coincident with the TeV gamma-ray source HESS J1813-178. We demonstrate that the nonthermal radio emission is due to a young shell-type supernova remnant (SNR), G12.8-0.0, and constrain its distance to be greater than 4 kpc. The X-ray emission is …
