Las Campanas Redshift Survey

The Las Campanas Redshift Survey was a 1990s survey of spectrographic redshifts of 26,000 galaxies, out to z = 0.2 (corresponding to about 0.75 Gpc). The survey was carried out using a multi-object spectrograph on the 2.5-meter du Pont Telescope at Las Campanas Observatory (LCO). The survey is considered an important early step toward determining the large scale structure of the universe.
