Enhanced Small-Scale Faraday Rotation in the Galactic Spiral Arms
Enhanced Small-Scale Faraday Rotation in the Galactic Spiral Arms
We present an analysis of the rotation measures (RMs) of polarized extragalactic point sources in the Southern Galactic Plane Survey. This work demonstrates that the statistics of fluctuations in RM differ for the spiral arms and the interarm regions. Structure functions of RM are flat in the spiral arms, while …
