The Disk-Halo Distinction of Galaxies Using Faraday Tomography

The Disk-Halo Distinction of Galaxies Using Faraday Tomography

Faraday tomography allows us to study the distribution and properties of the magnetoionic medium of galaxies through the Faraday effect. However, this can be achieved only after the Faraday spectrum is interpreted. One approach is using galactic ISM/magnetism models to investigate how characteristic...
