2002A&A...390..423K Relation between dust and radio luminosity in optically selected early type galaxies D. Krajnovic and W. Jaffe Sterrewacht Leiden, Postbus 9513, 2300 RA Leiden, The Netherlands Received 21 February 2002/Accepted 7 May 2002 Abstract. We have surveyed an optical/IR selected sample of nearby E/S0 galaxies with and without nuclear dust structures with the VLA at 3.6 cm to a sensitivity of 100 microJy. We can construct a Radio Luminosity Function (RLF) of these galaxies to ~10^19^ W Hz^-1^ and find that ~50% of these galaxies have AGNs at this level. The space density of these AGNs equals that of starburst galaxies at this luminosity. Several dust-free galaxies have low luminosity radio cores, and their RLF is not significantly less than that of the dusty galaxies. Key words: galaxies: elliptical and lenticular, cD - galaxies: luminosity function, mass function - galaxies: nuclei
