Until recently HESS J1731-347 was one of the dark sources discovered by H.E.S.S. instrument for which no clear counterpart at other wavelengths could be identified. Recently, a faint supernova remnant (SNR), G353.6-0.7, was identified positionally coinciding with the brightest hotspot of the TeV source HESS J1731-347, suggesting the SNR as the origin for the highenergy emission. XMM-Newton observations covering a fraction of the SNR revealed non-thermal X-ray emission that most likely can be interpreted as synchrotron emission from high-energy electrons accelerated by the SNR.This makes HESS J1731-347/G353.6-0.7 a new object in the small but growing class of shell-type SNRs with TeV emission, an important class because they can prove the role of SNRs as cosmic accelerators. We report the results of a mosaic of 18 different VLA pointings covering an area over 9 square degrees in size, along with a comparison with the X-ray emission.
