Measuring Magnetic Fields Near and Far with the SKA via the Zeeman Effect

Timothy Robishaw, Marta Nowotka, Tao-Chung Ching +7

Zeeman splitting in spectral lines -- both in emission and absorption -- provides direct estimates of magnetic field strength and direction in magnetized gas in our own Milky Way a…
