Abstract:
VLBA polarimetric observations of the steep-spectrum quasar 3C147 were made at four frequencies in the available 5 GHz band, from which polarization in one bright feature in the inner jet was detected. The rotation measure of this feature (
1300 rad m^-2) agrees with the known high rotation measure of the source, which makes it possible to remove the Faraday screen pixel-by-pixel and obtain the intrinsic magnetic field structure. The arch shape of B vectors suggests that a relativistic and distorted jet is being seen in projection.
