[24.04] An X-ray, Optical and Radio Survey of Supernova Remnants in Selected Nearby Galaxies

T.G. Pannuti, N. Duric (University of New Mexico), C.K. Lacey (Naval Research Laboratory)

We are conducting a survey of supernova remnants in selected nearby galaxies through observations at X-ray, optical and radio wavelengths. This research has drawn on archived ROSAT observations (with both the PSPC and HRI instruments), as well as published optical [SII] and H\alpha data and our own VLA observations at 6 and 20 cm. In addition, for some of our galaxies located at high declinations, we have supplemental Effelsberg 6 and 20 cm observations that augment the VLA data with large-scale radio structure information about the target galaxies. Our sample of galaxies includes two irregulars (IC 1613 and NGC 4449), four Sculptor Group galaxies (NGC 45, NGC 247, NGC 300 and NGC 7793), and several prominent spirals (M33, NGC 2403, NGC 6946 and M83), all of which exhibit recent or on-going massive star formation. Initial results and a brief discussion will be presented.
