Running many many cosmological simulations

A large number of cosmological simulations is important for the evaluation of the uncertainties in large-scale structure measurements. We generate 600 realisations of mock galaxy catalogues for the WiggleZ Dark Energy Survey using the COmoving Lagrangian Acceleration (COLA) method. This simulation method can compute large-scale structure reasonably well with only 10 time steps. With these mock catalogs, we update the Baron Acoustic Oscillation (BAO) cosmic distance measurement improved by the ‘reconstruction' technique. |
