ICRAR astronomers are involved in several ground-breaking surveys of the Universe with new and upgraded radio telescopes. In Australia, these include the Australian SKA Pathfinder (ASKAP), the Murchison Widefield Array (MWA), and the Parkes telescope; in China, the Five-hundred-meter Aperture Spherical radio Telescope (FAST); in the Netherlands, the APERTIF/WSRT telescope, and in the US, the Very Large Array and the Arecibo telescope.

The purpose of the various surveys is to understand the evolution of the Universe, the distribution of matter and the formation of galaxies and large-scale structure. Several projects are available, including the following:

 

  • Cosmological tests of the Lambda Cold Dark Matter model
  • Studying the evolution of the hydrogen content of galaxies
  • Interactions between galaxies and their effect on their evolution
  • Interactions of galaxies with intragroup and intracluster gas
  • The dark matter distribution in galaxies
  • Star formation inside and outside of galaxy discs
  • The relationship between galaxy properties and dark matter content
