The jet-disk symbiosis II. Interpreting the Radio/UV correlations in quasars FALCKE H., MALKAN M.A., BIERMANN P.L. <Astron. Astrophys. 298, 375 (1995)> =1995A&A...298..375F (SIMBAD/NED Reference)
ADC_Keywords: QSOs; Galaxies, radio; Keywords: galaxies: active - galaxies: jets - galaxies: nuclei - accretion disks Description: We investigate the correlation between the accretion disk (UV) luminosity and the radio core emission of a quasar sample, containing all PG quasars, also deriving empirical conversion factors from emission line luminosities to disk luminosities. This method allows us to investigate the radio properties of AGN on the absolute scale set by the accretion power. The tables contain the quasar (and radio galaxy) sample discussed in this paper (including the complete PG quasars sample) and give the derived `disk luminosities' of the UV-bump and 5GHz radio luminosities.
