Simulated skies for ASKAP
by Alan Duffy (Swinburne University of Technology)
One of the largest simulated universes ever created was 'viewed' through the expected configuration of the newly completed Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. Every galaxy expected to be detected in one of the planned surveys (all-sky WALLABY, deeper DINGO and ultra-deep DINGO extension) was coloured according to the efficiency with which they were forming stars and the size of the point scaled by the mass of HI detectable in the galaxy. The filamentary structure of the Cosmic Web is clearly visible with ~half million expected galaxies from these surveys. - Work published by Duffy, Meyer, Staveley-Smith, Bernyk, Croton, Koribalski, Gerstmann and Westerlund (2012, MNRAS 426, 3385).
