| Abstract: |
Supernova remnants (SNRs) have been detected over virtually the entire electromagnetic spectrum and are intimately associated with many processes associated with the interstellar medium, such as the deposition of chemically-enriched material and cosmic-ray acceleration. As the angular resolution and sensitivity capabilities of space-based X-ray observatories has improved, a remarkable new class of sources known as "mixed-morphology" SNRs (MM SNRs) has been firmly established in the literature. While models of supernova remnant evolution predict shell-like morphologies of SNRs at both X-ray and radio wavelengths, MM SNRs exhibit a center-filled X-ray morphology coupled with a shell-like radio morphology. MM SNRs all appear to be interacting with adjacent molecular clouds (as evidenced by infrared observations of molecules or maser observations): it is believed that these interactions may at least partially explain the origin of the contrasting morphologies seen for these objects. In this talk I will discuss properties of MM SNRs and results of pointed X-ray, infrared and radio observations of well-known members of this class of sources, including G352.7-0.1 and W28.
