We present the first results from the Quasar Feedback Survey, a sample of 42z<0.2, [O III] luminous AGN (L[O III]>10^42.1 ergs/s) with moderate radioluminosities (i.e. L(1.4GHz)>10^23.4 W/Hz; median L(1.4GHz)=5.9x10^23 W/Hz).Using high spatial resolution (~0.3-1 arcsec), 1.5-6 GHz radio images from theVery Large Array, we find that 67 percent of the sample have spatially extendedradio features, on ~1-60 kpc scales. The radio sizes and morphologies suggestthat these may be lower radio luminosity versions of compact, radio-loud AGN.By combining the radio-to-infrared excess parameter, spectral index, radiomorphology and brightness temperature, we find radio emission in at least 57percent of the sample that is associated with AGN-related processes (e.g. jets,quasar-driven winds or coronal emission). This is despite only 9.5-21 percentbeing classified as radio-loud using traditional criteria. The origin of theradio emission in the remainder of the sample is unclear. We find that both theestablished anti-correlation between radio size and the width of the [O III]line, and the known trend for the most [O III] luminous AGN to be associatedwith spatially-extended radio emission, also hold for our sample of moderateradio luminosity quasars. These observations add to the growing evidence of aconnection between the radio emission and ionised gas in quasar host galaxies.This work lays the foundation for deeper investigations into the drivers andimpact of feedback in this unique sample.
