• The Large Magellanic Cloud (LMC) is an ideal target for the study of an unbiased and complete sample of supernova remnants (SNR). This paper presents new X-ray and radio data of the LMC SNR candidate DEM L205, obtained by XMM-Newton and ATCA, along with archival optical and infrared observations. The authors use data at various wavelengths to study this object and its complex neighbourhood, in particular in the context of the star formation activity around the source. Supernova remnant features are detected at all observed wavelengths, soft and extended X-ray emission is observed, arising from a thermal plasma with a temperature kT between 0.2 kiloelectron-Volts (keV) and 0.3 keV. The authors definitely confirm DEM L205 as a new SNR. This object ranks amongst the largest remnants known in the LMC. The numerous massive stars and the recent outburst in star formation around the source strongly suggest that a core-collapse supernova is the progenitor of this remnant.
