Radio structure in z~0.25 radio-quiet QSOs

DOI

We present analysis of a homogeneous, optically selected, volume-limited (0.2<z~6kpc). In addition to revealing RQQ subgalactic morphology, we employ counterparts from legacy (FIRST at 1.4GHz) and recent (VLA Sky Survey at 3GHz) VLA surveys to investigate radio spectral indices and potential variability over decades-long timescales for a subset of the RQQs and for the cores of radio-intermediate and radio-loud sources in the parent sample of 178 QSOs. These results support the growing notion that the RQQ population is not a monolithic phenomenon but instead consists of a mixture of mainly starburst-powered and jet-powered galaxies.
