16 Aug 2000 | | Subject: | astro-ph | | Affiliation: | Imperial College, London, UK; Universite de Montreal, Canada | | Abstract: | We report on the first near-IR [Fe II] line imaging survey of extragalactic SNRs. Observations of a sample of 42 objects drawn from an optically-selected catalogue of SNRs in M33 provide evidence for a wide range in the [Fe II] 1.644 microns luminosities. This can be understood as being primarily due to variations in the chemical abundances and density of the local ISM, although shock conditions may also play a significant role. We briefly discuss how these results may be used to better calibrate the supernova rate of star-forming galaxies. | | Source: | arXiv, astro-ph/0008238 | | Services: | Forum | Review | PDF | Favorites | |
