These sources would have been previously classified as \"radio-quiet\" quasars based on upper limits from the Faint Images of the Radio Sky at Twenty Centimeters survey (1993-2011), but they are now consistent with \"radio-loud\" quasars ($L_{\\rm 3\\,GHz} = 10^{40 - 42} \\,\\, {\\rm erg} \\,{\\rm s}^{-1","authors_text":"Amy E.
