# Probing redshift-space distortions with phase correlations

Redshift-space distortions are a sensitive probe of the growth of large-scale structure. In the linear regime, redshift-space distortions are fully described by the multipoles of the two-point correlation function. In the nonlinear regime, however, higher-order statistics are needed to capture the full information of the galaxy density field. In this paper, we show that the redshift-space line correlation function--which is a measure of Fourier phase correlations--is sensitive to the nonlinear…

A novel alternative to the bispectrum is explored: the line correlation function (LCF), which specifically targets information in the phases of density modes that are invisible to the power spectrum, making it a potentially more efficient probe than the Bispectrum, which measures a combination of amplitudes and phases.
