We present polarization properties at 1.4 GHz of two separate extragalactic source populations: passive quiescent galaxies and luminous quasar-like galaxies. We use data from the Wide-Field Infrared Survey Explorer to determine the host galaxy population of the polarized extragalactic radio sources. The quiescent galaxies have higher percentage polarization, smaller radio linear size, and 1.4 GHz luminosity of 6 × 1021 < L1.4 < 7 × 1025 W Hz−1, while the quasar-like galaxies have smaller...[Show more]
