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…
The Behind The Plane Survey
Will Saunders, Kenton d'Mellow, Brent Tully +7
We have extended the PSCz to cover 93% of the sky, the practical limit for any catalogue based on the Point Source Catalog. The galaxy identifications are complete, and the core of…
PSCz-1.2 Jy Comparison: A Spherical Harmonics Approach
Luis Teodoro, Enzo Branchini, Carlos Frenk +8
We perform a detailed comparison of the IRAS PSCz and 1.2-Jy spherical harmonic coefficients of the density and velocity fields in redshift space. The monopole terms predicted from…
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…
