Measuring the Redshift-space Distortions by Cross-correlating the Density Fields Before and After Reconstruction
In this work, we develop a theoretical model for the cross-power spectrum of the matter density field before and after standard baryonic acoustic oscillation reconstruction. Using this model, we extract the redshift-space distortion parameter from the cross-power spectrum. The model is validated aga...
