Scientific paper
Tables and radio brightness distribution maps are presented from observations of the central radio continuum sources in 81, mostly spiral, galaxies obtained with the Very Large Array at 6.0 cm. A simple classification scheme is used to characterize the radio structure, and the dependence of radio morphology on other galaxy properties is investigated. Early, Hubble-type galaxies are found to mostly exhibit strong and simple central sources, while late-type galaxy central sources are generally weak, complex or absent. A correlation was also found with the color, or stellar population, of the center of a galaxy, where galaxies with red centers have strong and simple radio sources while those with blue centers show complex and weak central sources. The central components of the sources sampled have a median size of 125 pc.
