Abstract: X-ray observations unveiled the existence of enigmatic point-like sources atthe centre of young supernova remnants SNRs. These sources, dubbed CentralCompact Objects CCOs, are thought to be neutron stars formed by the supernovaexplosion. However, their multi-wavelength phenomenology is surprisinglydifferent from that of most young neutron stars.The aim of this work is tounderstand the nature of the CCO 1WGA J1713.4-3949 in the G347.3-0.5 SNR,through deep optical and IR observations, the first ever performed for thissource.By exploiting its derived Chandra X-ray position we carried out opticalBVI observations with the NTT and Adaptive Optics IR JHKs observations withthe VLT. We detected two faint I~23.5, I~24.3. patchy objects in the NTTimages, close to the Chandra error circle. They were clearly resolved in ourVLT images which unveiled a total of six candidate counterparts 17.8
