Redshift Distortions and Clustering in the PSCz Survey

Abstract

We have constrained the redshift-distortion parameter $\beta \equiv {\Omega }^{0.6}/b$ and the real-space power spectrum of the IRAS PSCz survey using a spherical-harmonic redshift-distortion analysis combined with a data compression method which is designed to deal with correlated parameters. Our latest result, $\beta =0.4\pm 0.1$, strongly rules out $\beta =1$.
