Based on its energy-dependent morphology the initially unidentified very highenergy (VHE; E>100 GeV) gamma-ray source HESS J1303-631 was recently associatedwith the pulsar PSR J1301-6305. Subsequent detection of X-ray and GeVcounterparts also supports the identification of the H.E.S.S. source as evolvedpulsar wind nebula (PWN). We report here on recent radio observations of thePSR J1301-6305 field of view (FOV) with ATCA dedicated to search for the radiocounterpart of this evolved PWN. Observations at 5.5 GHz and 7.5 GHz do notreveal any extended emission associated with the pulsar. The analysis of thearchival 1.384 GHz and 2.368 GHz data also does not show any significantemission. The 1.384 GHz data reveal a hint of an extended shell-like emissionin the PSR J1301-6305 FOV which might be a supernova remnant. We discuss theimplications of the non-detection at radio wavelengths on the nature andevolution of the PWN as well as the possibility of the SNR candidate being thebirth place of PSR J1301-6305.
