Models of the depolarization asymmetry

The simplest interpretation of the depolarization asymmetry is an orientation effect giving a different path length for the radiation from the two sides of the source through a magnetized gaseous halo, leading to larger rotation measure (RM) variations on the counterjet side of the source. In this section I briefly consider other possible causes of the depolarization which might either form the basis of an alternative interpretation or introduce additional complications and noise.
