| 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
