Understand
The North Polar Spur (NPS) is the brightest filament of Loop I, a large circular feature in the radio continuum sky.
- In this paper, a model consisting of two synchrotron emitting shells is presented that reproduces large-scale structures revealed by recent polarization surveys.
- The polarized emission of the NPS is reproduced by one of these shells.
- The other shell, which passes close to the Sun, gives rise to polarized emission towards the Galactic poles.
