The Fan Region at 1.5 GHz โ I. Polarized synchrotron emission extending beyond the Perseus Arm
The Fan Region is one of the dominant features in the polarized radio sky, long thought to be a local (distance < 500 pc) synchrotron feature. We present 1.3-1.8 GHz polarized radio continuum observations of the region from the Global Magneto-Ionic Medium Survey (GMIMS) and compare them to maps of โฆ
