Scientific paper

We propose to observe two supernova remnants interacting with molecular gas. One has associated 1720 MHz maser emission and some central X-ray emission; both show IR emission nearby. X-ray imaging and spectroscopy should allow classification of both remnants, with characterization of central emission. Association of observed 24 micron emission may be confirmed or ruled out; if confirmed, joint IR/X-ray modeling can allow important inferences about dust. Inference of shock speeds, densities, and remnant ages should allow better understanding of the conditions under which dust emission can be seen and 1720 MHz masers produced, and should improve our overall picture of the evolution of mature supernova remnants and their interaction with the interstellar medium.
