• The Large Magellanic Cloud (LMC) is rich in supernova remnants (SNR), which can be investigated in detail with radio, optical, and X-ray observations. SNRJ0453-6829 is an X-ray and radio-bright remnant in the LMC, within which previous studies revealed the presence of a pulsar wind nebula (PWN), making it one of the most interesting SNRs in the Local Group of galaxies. The authors study the emission of SNRJ0453-6829 to improve their understanding of its morphology, spectrum, and thus the emission mechanisms in the shell and the PWN of the remnant. They obtained new radio data with the Australia Telescope Compact Array and analysed archival XMM-Newton observations of SNRJ0453-6829. They studied the morphology of SNRJ0453-6829 from radio, optical, and X-ray images and investigated the energy spectra in the different parts of the remnant. Their radio results confirm that this LMC SNR hosts a typical PWN.
