A new imaging technique has been developed that can reconstruct standard two-dimensional radio images as three-dimensional ones.
This technique has the potential to provide information about the 3D structures of polarized radio sources, such as the jet-like features of galactic black holes.
The technique utilizes the measurement of Faraday rotation to determine the relative distance between the emitting region and the observer.
The study suggests that the 3D reconstructions may challenge existing physical models of how radio galaxies form and how the jets from black holes interact with the surrounding medium.
