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.
