Abstract
![CDATA[The 30 Dor C superbubble (SB) in the Large Magellanic Cloud is notable for its bright shell of non-thermal X-ray emission. The southeastern region is also known to exhibit significant thermal emission with metal enhancements indicating the presence of a supernova remnant (SNR). However, a detailed treatment and characterisation of the thermal emission has not yet been performed. In this work, we present the analysis of the ample XMM-Newton data available for 30 Dor C (flarefiltered exposure times of 420 ks EPIC-pn, 556 ks EPIC-MOS1, 614 ks EPIC-MOS2) to attempt to isolate and identify any X-ray emission due to an SNR. In addition, an analysis of the nonthermal emission will be presented and discussed in the context of emission mechanisms previously suggested in the literature (i.e., non-thermal bremsstrahlung and synchrotron). Two SNRs were found to be contributing to the thermal emission in 30 Dor C. The most apparent is manifest as a prominent arc in the 1-2 keV energy range, which shows strong emission lines of α-process elements in its spectrum, consistent with a core-collapse remnant. Its X-ray morphology points to a location outside the SB. The second SNR is likely an interior SNR interacting with the shell wall.]]
