Parsec-scale rotation-measure distribution in the quasar 3C147 at 8 GHz.

Abstract (from CDS):

VLBA polarization observations of the high-rotation-measure source 3C147 were made at four frequencies in the available 8 GHz band. The distribution of total flux and rotation measure across the source has been imaged. The rotation measure of the inner jet of the source (~-1800rad/m2) is consistent with previous results. After removing the rotation of the plane of polarization due to a foreground screen, the derived intrinsic magnetic field structure of the source on parsec scales is roughly transverse to the predominant jet direction, indicating the presence of relativistic shocks or a dominant toroidal jet B-field component.
