Scientific paper

We report principal results of a search for extended 6 cm continuum emission from 12 radio-quiet quasars using the Very Large Array (VLA). We report evidence for extended emission in QSO 1821+643 and tentative detection of similar structure in three others. We suspect that a low-radio power AGN resides in the center of the QSO 1821+643 host galaxy, ejecting plasma into a dust/gas-rich environment and creating extended (≍76 kpc) low brightness radio emission. However, star formation may also be a contributor to the radio as well as to the far infrared (FIR) luminosity of this galaxy.
