Evidence that the AGN dominates the radio emission in z ~ 1 radio-quiet quasars
Published 2017“…Published by Oxford University Press on behalf of the Royal Astronomical Society.In order to understand the role of radio-quiet quasars (RQQs) in galaxy evolution, we must determine the relative levels of accretion and star-formation activity within these objects. …”
