AKARI Observations of Supernova Remnants

We have been doing infrared studies of supernova remnants (SNRs) using the AKARI satellite. We observed seventeen SNRs using the near/mid-infrared camera IRC and/or the far-infrared camera FIS in a framework of the AKARI mission program ISMGN. The target SNRs include Crab-like SNRs, young core-collapse SNRs, and SNRs interacting with molecular clouds. We have also studied SNRs in the Large Magellanic Cloud (LMC) using the AKARI large-scale LMC survey data. We present the contents of our study and some main results, including serendipitous discoveries. We show that the AKARI IRE colors are useful for exploring the nature of the IR emission from SNRs and also the nature of SNRs.
