Inside the magnetic tunnel: How radio maps reveal the structure of our Milky Way’s magnetic field

Our view of the sky is a complicated superposition of objects that are both near and far. Disentangling this information is challenging, but essential to a complete understanding of our Galaxy, and the Universe. In this talk, I will discuss the brightest, large-scale, diffuse, polarized radio features in the sky, the North Polar Spur and the Fan Region, and present a model that explains these features as very local structures in our Galaxy’s magnetic field. I will also discuss some of the challenges with and present some of the ways that we can understand the global structure beyond our Local Bubble.
