AbstractThis is a design study into the capabilities of the Australian Square Kilometre Array Pathfinder in performing a full-sky low redshift neutral hydrogen survey, termed WALLABY, and the potential cosmological constraints one can attain from measurement of the galaxy power spectrum. We find that the full sky survey will likely attain 6 × 105redshifts which, when combined with expectedPlanckCMB data, will constrain the Dark Energy equation of state to 20%, representing a coming of age for
