SAS Lecture(via Zoom): Dark matter - successes and struggles of a theory

About this event :


There are several lines of evidence pointing to the existence of an as yet elusive dark matter which is more abundant in the Universe on average than the ordinary stuff of gas, stars and planets.
Despite the persistent lack of a plausible particle candidate, the LCDM cosmological theory has been remarkably successful in describing the large scale structure of the Universe. The biggest current challenges to this theory are manifest on the scale of dwarf galaxies.

  • How can we measure a substance we cannot see?
  • What can a handful of puny nearby galaxies tell us about the Universe as a whole?

These are the questions I’m tackling with the help the cutting-edge cosmological computer simulations and observations taken on radio telescopes such as the Very Large Array and the Australian Square Kilometre Array (SQM) Pathfinder.
