The GMIMS survey at Parkes
by Wolleben et al.
The Global Magneto-Ionic Medium Survey (GMIMS) used the Parkes 64m to study the polarized radio emission from our Galaxy and characterise the strength and configuration of the Galactic magnetic field. The data product from this survey that is without precedent is the Faraday-depth cube. The image above shows the zeroth moment of Faraday depth from this cube, The zeroth moment shows the total polarized brightness integrated over the full range of Faraday depth and is a representation of the locations of bright polarized emission. More details are given in the paper by Wolleben et al. (2019) in the Astronomical Journal.
