Title: Investigation of Supernova Remnants in nearby galaxies

Abstract: We propose to obtain optical spectra of photometrically selected SNRs in 4 nearby galaxies (NGC,45, NGC,55, NGC,1313 and NGC,7793) based on narrow-line imaging. 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.
