Reconstructing PSCz with a Generalised PIZA
Helen Valentine, Will Saunders, Andy Taylor
We present a generalized version of the Path Interchange Zel'dovich Approximation (PIZA), for use with realistic galaxy redshift surveys. PIZA is a linear particle-based Lagrangian…
The IRAS view of the Local Universe
Will Saunders, Kenton D'Mellow, Helen Valentine +8
We summarise results for the predicted density and peculiar velocity fields from the PSCz survey. We have used a generalisation of the Path Interchange Zeldovich Approximation to d…
Density and Velocity Fields from the PSCz Survey
Will Saunders, Enzo Branchini, Luis Teodoro +17
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. We find a significant…
Reconstructing PSCz with a Generalized PIZA
Helen E. M. Valentine, Will Saunders, Andy Taylor
We present a generalized version of the Path Interchange Zel'dovich Approximation (PIZA; Croft and Gaztanaga 1997; hereafter CG97), which may be used to reconstruct density and vel…
