Abstract : The existence of a galactic magnetic field is presupposed by theories describing the polari zation of starlight, the emission of galactic radio noise, and the behavior of cosmic rays. The line-of-sight component of the galactic mag netic field causes a splitting of the radiation into left-hand and right-hand circularly polar ized waves. The observed profile and the ex pected difference profile for the two observed sources, Cas A and Taurus A, are shown. (Author)
