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…
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…
A Non Parametric Model for the Cosmic Velocity Field
E. Branchini, L. Teodoro, C. S. Frenk +10
We present a self consistent nonparametric model of the local cosmic velocity field based on the density distribution in the PSCz redshift survey of IRAS galaxies. The error analys…
Likelihood Analysis of the Local Group Acceleration
I. Schmoldt, E. Branchini, L. Teodoro +10
We compute the acceleration on the Local Group using 11206 IRAS galaxies from the recently completed all-sky PSCz redshift survey. Measuring the acceleration vector in redshift spa…
