Abstract:
The Palomar survey has served as a basis for the study of nuclear activity in nearby galaxies. Results show that there is a plethora of activity as probed by the spectral-line characteristics. We here present our results on the follow-up radio surveys of galaxies classified as LINERs and composite, with special emphasis on possible low luminosity AGN activity. In a broader context, the Palomar radio luminosity function is compared with selected samples of Seyferts and moderate redshift AGN. We also present our preliminary results on the detection and modeling of some of the smallest extragalactic jets known, produced in composite galaxies. Finally, we present our project aimed at studying the relative contribution of circum-nuclear stars to the spectra of low luminosity AGN.
