An X-ray Investigation of Four SNR Candidates in the LMC

The Large Magellanic Cloud (LMC), with its low foreground absorption andproximity, offers the ideal site to study a large sample of SNRs in detail, bothspatially and energetically. It is possible to obtain a relatively completesample of SNRs in the LMC to examine both global properties and the subclassesof SNRs. Toward this goal, we are identifying new SNRs using multiwavelengthdata. Our new SNR candidates are generally fainter than the known sample, andmay represent a previously missed population. Here we request XMMNewtonobservations of four optically identified SNR candidates. These observationswill allow us to confirm the nature, study the physical structure and evolution,and use the abundance anomaly to investigate types of supernova progenitors of these new SNRs. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
