| Sumario: | Quasilinear rotations in the polarization position angle of two extragalactic active radio sources have been observed recently at 1435 MHz. The observations may be interpreted in terms of relativistic jet models. In this context, the observed polarization position angle rotation results from the propagation of a strong shock wave along a relativistic force-free jet with a nonaxisymmetric magnetic field configuration. Several internal parameters of the sources are estimated and matched with independent high-resolution observations. |
