Abstract
Absorption lines at 21 cm are detected in the Stokes Q and U components of the Galactic synchrotron background. The lower limit distance implied for the emission region is 2 kpc in the direction (l, b) = (3295, +115). The Australia Telescope Compact Array has the capability of mapping this absorption over large areas of the Galactic plane. Observations like these have the potential to reveal the three-dimensional structure of the Galactic synchrotron emission throughout the Milky Way disk.Keywords
