Abstract
SYNCHROTRON radiation from the Milky Way at radio wavelengths is linearly polarized if the magnetic field in the emitting region is in the same direction throughout the line of sight, and if the Faraday rotation is small within the emitting region. Observations at λ0.21 m show-polarization up to 25 per cent in a direction somewhat inclined from the perpendicular to the spiral arm; at λ0.73 m the percentage polarization is less, and the polarized area is also less, indicating that Faraday rotation is becoming important. The polarization at longer wavelengths has so far remained unknown, in spite of several attempts to measure it1–4.
