Abstract
We find, using narrow-band imaging, a direct spatial coincidence between the location of bright [Fe II] 1.64µm line emission and compact steep spectrum radio sources in the nuclear region of the starburst galaxy NGC 253. For a large sample of active galaxies (starburst, LINER and Seyferts) we also find a strong correlation between the integrated nuclear [Fe II] 1.64µm and 6cm radio luminosity. Both the spatial and integrated relations are interpreted in terms of supernova activity. There is evidence that extragalactic supernova remnants can be more luminous than their counterparts in the Galaxy.
