Application of Data Compression Methods to the Redshift-space distortions of the PSCz galaxy catalogue
A. N. Taylor, W. E. Ballinger, A. F. Heavens +1
We apply a spherical harmonic analysis to the Point Source Redshift Survey (PSCz), to compute the real-space galaxy power spectrum and the degree of redshift distortion caused by p…
Redshift Distortions and Clustering in the PSCz Survey
W. E. Ballinger, A. N. Taylor, A. F. Heavens +1
We have constrained the redshift-distortion parameter and the real-space power spectrum of the IRAS PSCz survey using a spherical-harmonic redshift-distortion a…
A microlensing search for cold molecular clouds in Virgo
H Tadros, S J Warren, P C Hewett
We report preliminary results from a first season of photometric monitoring of 600 quasars behind the Virgo galaxy cluster with the aim of detecting microlensing by the cluster dar…
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…
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…
