A Unified Model for the Fan Region and the North Polar Spur: A Bundle of Filaments in the Local Galaxy
Abstract We present a simple, unified model that can explain two of the brightest, large-scale, diffuse, polarized radio features in the sky, the North Polar Spur (NPS) and the Fan Region, along with several other prominent loops. We suggest that they are long, magnetized, and parallel filamentary structures that surround …
