redshift survey

(survey of the universe aiming at three dimensions)

A redshift survey is an astronomical survey gathering redshifts of galaxies, galaxy clusters, and other phenomena (e.g., supernovae) aiming to map the universe in three dimensions. It produces a literal map in redshift space that can be interpreted as three space dimensions using Hubble's law.
