Abstract
Supernova remnants (SNRs) are of vital importance to the physical and chemical evolution of the interstellar medium (ISM). The expanding shell of the remnants imparts kinetic energy to the surrounding ISM as well as enriching it with the metals fused in the cores of their progenitor stars. Thus, an understanding of these objects is crucial to the understanding of star formation and matter recycling in galaxies. We have been studying SNRs in the Magellanic Clouds (MCs) in greater detail using combined optical, radio, and X-ray observations. The X-ray selected candidate SNRs 1RXS J053353.6-720404 and [HP99] 1139 were observed by XMM-Newton in May 2012. Both candidates are readily confirmed as bona fide X-ray SNRs due to their soft thermal emission and morphology. [HP99] 1139 is also notable due to the bright Fe-rich gas in its interior, a feature observed in several evolved LMC SNRs and is typical of a Type Ia SN progenitor. In this poster we present the detailed analysis of these remnants, including a comparison of the X-ray emission to multiwavelength data to better understand their spectral and morphological properties.
