Title: Investigation of Supernova Remnants in nearby galaxies

Abstract: \beginabstract We propose to obtain optical spectra of photometrically selected SNRs in 5 nearby galaxies (NGC 3077, NGC 4214, NGC 4395, NGC 4449 and NGC 5204), based on narrow-line imaging. In that way, we will confirm these identifications and obtain an accurate sample of extragalactic SNRs. These observations will provide a 2 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.
