Las Campanas Redshift Survey

Redshift pie chart

The Las Campanas Redshift Survey observed redshifts for more than 20,000 galaxies in the South and North galactic polar caps. Plotted above is a dot for each galaxy showing its right ascension (RA) and recession velocity (cz). The color of the dot shows which declination stripe (Dec) the galaxy is in. The dots for more distant galaxies are bigger to allow for the fact that only a small fraction of all galaxies are luminous enough to be seen at great distances.

Note that while there are many voids and great walls with sizes of 100 Mpc (6500 km/sec) the large scale pattern is more uniform. The LCRS did not see "super Great Walls" or "super voids".
