Both in the Faraday Rotation Measure and the intrinsic polarization angle, new features are revealed to indicate a helical magnetic field operating along the jet of the bright active galactic nuclei 3C 273. The helical field has been suggested to be related to the formation and collimation of jets by magnetohydrodynamic models. The distribution of the RM shows a systematic gradient with respect to the jet axis, which is expected by a helical magnetic field. In addition, the helical field can consistently explain two types in the direction of the projected magnetic field: parallel and perpendicular to the jet axis. Further, if the helical magnetic field is generated by winding up of an initial field by rotation of the accretion disk, we can uniquely determine the direction of the disk rotation, since the jet is approaching us.

    VLSS J0318.9+5755 (the Treble Clef) is a radio phoenix with ultra-steep spectrum in a massive merging cluster at z≈0.117 in the Zone of Avoidance, shaped by ICM gas motions that may also power a candidate radio halo.

    The magnetic field in Abell 2255 shows ordered, region-dependent orientations inferred from synchrotron intensity gradients, with radial fields in bridges and tangential fields in relics.
