Scientific paper
A sample of 100 Sbc galaxies has been observed at different wavelengths and resolutions. The ultimate aim of the project is to probe the origin of their nuclear activity (e.g., blackhole, starbust, etc.). The results from radio observations with the VLA (New Mexico) at 20 and 6 cm wavelength, with a resolution of 1-2 arc sec, for the inner kpc of nineteen sources are presented. Six of the galaxies show extended emission consistent with starburst activity. The remaining thirteen are unresolved or marginally resolved compact sources. Their steep spectra indicate synchrotron emission. They show total nuclear energies similar to those found for a sample of Seyfert galaxies. Optical spectroscopic observations with a similar resolution to the radio data have been made for approximately 90 galaxies. A sample of the derived rotation curves is included.
