Title: Investigation of Supernova Remnants in nearby galaxies

Abstract: We propose to obtain optical spectra of photometrically selected SNRs in 6 nearby galaxies (NGC 2403, NGC 3077, NGC 4214, NGC 4395, NGC 4449 and NGC 5204) 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.
