On The Validity of the Streaming Model for the Redshift-Space Correlation Function in the Linear Regime
Karl B. Fisher
The relation between the galaxy correlation function in real and redshift-space is derived in the linear regime by an appropriate averaging of the joint probability distribution of…
Wiener Reconstruction of The Large Scale Structure
S. Zaroubi, Y. Hoffman, K. B. Fisher +1
The formalism of Wiener filtering is developed here for the purpose of reconstructing the large scale structure of the universe from noisy, sparse and incomplete data. The method i…
Wiener Reconstruction of Density, Velocity, and Potential Fields from All-Sky Galaxy Redshift Surveys
Karl Fisher, Ofer Lahav, Yehuda Hoffman +2
We present a new method for recovering the cosmological density, velocity, and potential fields from all-sky redshift catalogues. The method is based on an expansion of the fields…
Wiener Filtering of the COBE DMR Data
Emory F. Bunn, Karl B. Fisher, Yehuda Hoffman +3
We derive an optimal linear filter to suppress the noise from the COBE DMR sky maps for a given power spectrum. We then apply the filter to the first-year DMR data, after removing…
