Connecting magnetic towers with Faraday rotation gradients in active galactic nuclei jets
The idea that systematic Faraday Rotation gradients across the parsec-scale jets of active galactic nuclei (AGNs) can reveal the presence of helical magnetic (|${\boldsymbol B}$|) fields has been around since the early 1990s, although the first observation of this phenomenon was about ten years later. These gradients are taken to …
