Exploring the Dark Universe

A close up of the PMT arrays used in ZEPLIN-III, one of the world’s leading direct search instruments. It is a two-phase xenon-based detector and is located at the Boulby mine in the North East of England.

Dr Alex Murphy, a Reader in the School's Nuclear Physics group, will be delivering a lecture on Dark Matter and Dark Energy as part of the University of Bath's Millennium Lectures series. The series forms part of the programme of the International Year of Chemistry.

  • Venue Bath University
  • Date February 9th 2011
  • Summary 'The materials of the everyday world around us are composed of the chemical elements, in turn formed from atoms and their substructures. Yet when we examine the motions of stars and galaxies we are led to the remarkable conclusion that the energy content of the Universe as a whole is completely dominated by fundamentally different materials, dubbed "dark matter" and "dark energy". What is the evidence for this remarkable statement? What are these new entities? And can we prove they really do exist? Find out how an experiment deep in a potash mine near Whitby might be about to provide some of the answers.'

You can read more about the work in the Boulby potash mine in this article in the Mail On Sunday.

The 3 simulations in the gallery below were produced by the Millennium Project, with each showing slices of Dark Matter distribution. The slices through the density field are all 15 Mpc/h thick. Three panels are shown for each redshift: subsequent panels zoom in by a factor of four with respect to the previous ones.
