Title: Investigation of Supernova Remants in Nearby Galaxies

Abstract: We propose to obtain deep narrow-band H(alpha) and [SII] images in nearby galaxies (M81, NGC 55, NGC 628, NGC 1313, NGC 6946, NGC 7793). These observations are in the context of an on-going project to study the SNR populations detected in multi-wavelength observations of nearby galaxies.They will provide a ~1 order-of-magnitude improvement in sensitivity over similar previous surveys and therefore a more complete and representative picture of the SNR populations in different galactic environments. They will supplement existing deep Chandra observations by confirming the X-ray classification of the identified sample of thermal X-ray SNRs and will allow us to link their X-ray properties (temperature, luminosity) to their optical properties (H(alpha) luminosity, density) and local environment.
