IPAC Seminar: Sarah White -- Radio-Quiet Quasars in the VIDEO Survey

The new VISTA Deep Extragalactic Observations (VIDEO) Survey is used to select a sample of radio-quiet quasars (RQQs), to depths ~4 magnitudes fainter than SDSS. Over a fifth of them are confirmed spectroscopically, and a statistical analysis is used to extract radio fluxes at their positions, below the flux limit of VLA radio data. We aim to disentangle radio emission due to AGN accretion and that due to star-formation. We can then determine how jet production may depend on accretion rate for low-power radio sources, and also investigate whether star-formation activity is related to the accretion on to the central supermassive black hole.
