Randomized trial reveals velocity fields from redshift space information, suggesting effective prediction methods.

This research aims to develop a method for predicting velocity fields based on galaxy distributions in redshift space.
Applied a modified kinematic Zel'dovich relation to derive velocity and density fields from redshift space data.
Utilized separation of variables with spherical harmonics to solve the differential equation.
Computed velocity dipole predictions from the 1.2 Jy IRAS survey and compared them with measured velocities.
Achieved a good coherence between predicted and measured velocity dipoles, indicating effective prediction methods.
Estimated β value was 0.6 ± 0.2, suggesting a consistent relationship between local galaxy distribution and gravity field.

Nusser et al. (1994) studied this question.
