Scientific paper

The radio continuum emission from the central region of a sample of interacting spiral galaxies (92 galaxies of which 60 in a complete sample) and of a control sample of more isolated spiral galaxies (94) was observed with the Very Large Array at 1.49 GHz. The angular resolution of the observations is ≡1arcsec.3 and the detection limits are ≡0.6 mJy and ≡1.5 mJy for point sources and extended sources with a half power size of 10arcsec respectively. This survey, in combination with published optical spectroscopy, provides the data for a detailed comparison of the central region in interacting and more isolated spiral galaxies.
