Gradients of excitation in the nuclei of starburst galaxies
The use of long-slit spectroscopy at high spectral and spatial resolution has made it possible to measure gradients of gaseous excitation and also velocity fields in a sample of four bright nuclear starburst galaxies selected from the sample of Balzano (1983). Variations are found not only in the intensity but also in the quality of the emission
