IRAS PSCz v.s. 1.2-Jy Velocity and Density Fields: A Spherical Harmonics Comparison
Luis Teodoro, Enzo Branchini, Carlos Frenk
We have used the two IRAS redshift surveys, 1.2-Jy (Fisher et al 1995) and PSCz (Saunders et al 2000), to model the linear velocity fields within a redshift of 8,000 km/s and have…
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…
Velocity Fields from IRAS-PSCz survey
E. Branchini, C. S. Frenk L. Teodoro, I. Schmoldt +9
We present a self-consistent nonparametric model of the cosmic velocity field based on the spatial distribution of IRAS galaxies in the recently completed all-sky PSC redshift s…
