Recovering 3D Magnetic Turbulence from Single-frequency Faraday Screens
The study explores using a directional spectrum derived from single-frequency radio polarization maps to recover 3D magnetic turbulence statistics in both the source and Faraday rotation regions. The method shows that this spectrum is sensitive to the Faraday screen's slope, providing an observer-friendly way to determine if data samples the emitting region or the rotation volume.
