The radio galaxies and the magnetic field in Abell 119.

Abstract (from CDS):

We present new, multiwavelength Very Large Array observations of the 3 radio galaxies in the cluster Abell 119: 0053-015, 0053-016 and 3C 29. The first two radio galaxies, which lie close to the cluster center, show a narrow-angle-tailed structure, with many twists in the tails. The third radio source is located at the cluster periphery, and shows an undistorted FRI morphology. All three radio sources are strongly polarized at the highest frequencies, and all three show both more depolarization and higher Faraday Rotation Measures with increasing proximity to the cluster center. We interpret this polarization behaviour as induced by the magneto-ionized intracluster medium, whose magnetic field is estimated to be in the range 5-10µG.
