Wiener Reconstruction of Galaxy Surveys in Spherical Harmonics
O. Lahav, K. B. Fisher, Y. Hoffman +2
The analysis of whole-sky galaxy surveys commonly suffers from the problems of shot-noise and incomplete sky coverage (e.g. at the Zone of Avoidance). The orthogonal set of spheric…

A Spherical Harmonic Approach to Redshift Distortion and a Measurement of Omega from the 1.2 Jy IRAS Redshift Survey
Karl B. Fisher, Caleb A. Scharf, Ofer Lahav
We present a formalism for analysing redshift distortions based on a spherical harmonic expansion of the density field. We use a maximum likelihood estimator for the combination of…
