Working Groups

  • Milky Way

    We study the magnetic field in our own Galaxy, the Milky Way, by using pulsars and looking at diffuse polarized emission. Understanding the structure of the local magnetic field folds into other science work as the Milky Way provides a foreground along essentially all lines of sight.

  • Nearby Galaxies

    We study magnetic fields in our neighbour galaxies and have selected a sample of galaxies of different morphological types, inclinations, masses and star-formation rates.This also helps us to better understand the magnetic field of our own Galaxy, which cannot be seen from outside. We investigate how magnetic fields, along with star formation, gravity, interactions between galaxies and other dynamical processes, play a role in the evolution of galaxies – and vice versa, how cosmic evolution shapes galactic magnetic fields.

  • Giant Radio Galaxies

    These gigantic radio sources are powered by monstrous supermassive black holes (SMBH). The jets from these SMBH pump energy back into the local environment, but the sheer extent of the radio emission means that they extend way beyond the host galaxy. Studying the magnetic fields in these objects allows us to learn about the magnetic field external to galaxies.

  • Intergalactic filaments

    Studying magnetic fields on these largest of scales allows us to probe the origins of cosmic magnetism in the Universe. However, the technical challenges of detecting magnetic fields in these very faint, very sparse regions mean this is a tough challenge -- one that only the next generation of radio telescopes have the capability of tackling.
