dc.descriptionA VLA survey of nearby LINER galaxies at 15 GHz has revealed the presence of a compact radio core in many sources. The cores seem to be correlated with the optical activity. Follow-up VLBA observations of the ten brightest sources confirm that these cores have brightness temperatures >10^8 Kelvin, thus confirming their AGN nature. The two brightest radio sources (NGC6500 and NGC4278) show extended jet-like structures and the flat spectral indices of all cores also suggest a jet nature rather than emission from an ADAF.
