[132.13] A FUSE Survey of Supernova Remnants in the Magellanic Clouds

We report the progress to date from an ongoing unbiased ultraviolet survey of supernova remnants in the Magellanic Clouds using the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite. Earlier work with FUSE has indicated that optical and/or X-ray characteristics of supernova remnants are not good predictors of the objects that will be bright in the ultraviolet. We obtained spectra of as complete a sample of Magellanic Cloud SNRs as was possible within the constraints of a FUSE survey program. We proposed 39 objects in the Large Magellanic Cloud and 11 objects from the Small Magellanic Cloud, with a standard request of 10 ks per object using the FUSE 30\arcsec\ square aperture. Actual observations were both higher and lower than this standard request, and so the depth of exposure varies between targets. To date, 39 objects have been observed in the survey and C~III \lambda977 or O~VI \lambda1032 emission have been detected in 15 of them. Thus, our survey has more than tripled the number of UV-detected SNRs in the Magellanic Clouds (from 7 to 22). We compare the optical, X-ray, and UV properties of the entire sample to search for systematic trends that may shed light on the relationship among the emission in these different wavebands. We also highlight the UV characteristics of selected objects.
