RADIO-EMISSION FROM IRAS-SELECTED QUASARS

All six southern quasars discovered in the IRAS point source catalogue have been detected with the Molonglo Observatory Synthesis Telescope at 843 MHz, with flux densities in the range 10-50 mJy. The corresponding radio luminosities indicate that these are typical radio-quiet quasars. The ratio of radio to far-infrared (FIR) luminosity for the six objects places them on the remarkable correlation between radio and FIR luminosity that exists for low surface brightness and early-type spiral galaxies and for galaxies having high rates of star formation. Unless this is a coincidence or a selection effect, it appears that the physical processes underlying the radio-FIR correlation, often identified as being related to star formation, dominate both the FIR and the radio emission from these IRAS quasars.
