WebDensity and Velocity Fields from the PSCz Survey Saunders, W. ; Collaborators We present the results for the predicted density and peculiar velocity fields and the dipole from the PSCz survey of 15,000 IRAS galaxies over 84% of the sky. WebWe obtain a continuous galaxy density field by smooth- ing the discrete distribution of PSCz galaxies on a N 3 grid. We use a Gaussian kernel with smoothing radius, Rsm , varying from 5 to 15 h−1 Mpc. The grid size that 2.2 N-body Simulations we use is …
