Abstract
Using recent high-resolution radio observations of a large sample of Seyfert galaxies (Roy et al. 1994), we analyze the relations between the compact radio core emission and several nuclear and host galaxy properties. Seyfert nuclei hosted in early-type galaxies or in object with nearby companions show stronger radio cores than the norm. Radio core emission show some correlation with total radio emission and with tracers of nuclear activity (mid-IR, hard X-ray and narrow-line emissions). This favours the view that Seyfert radio cores are powered by AGN rather than by radio supernovae.
