The Large Magellanic Cloud (LMC), with its low foreground absorption and relative proximity, offers the ideal laboratory for the study of a large sample of supernova remnants (SNRs) in moderate detail. The proximity enables detailed spatial studies of the remnants in the sample, and the accurately known distance allows for analysis of the energetics of each remnant. In addition, the wealth of wide-field multiwavelength data available, from HI maps to optical emission-line images and broad band photometry to global X-ray mosaics, provides information about the contexts and environments in which these remnants are born and evolve.
It is possible to obtain a relatively complete sample of SNRs in the LMC and not only study the global properties of the sample but also study the subclasses in detail (e.g., sorted by X-ray morphology or by progenitor SN type). Toward this goal, we have been identifying new SNRs using combined optical, radio, and X-ray observations. We report on observations of six intriguing SNR candidates which probe a range of interstellar environments, three which are away from HII regions and three which are embedded in or near regions with significant HII emission.
