The Power Spectrum of Galaxy Clustering in the Las Campanas Redshift Survey

The Las Campanas Redshift Survey (LCRS) contains 23, 697 galaxies, with an average redshift z \ 0. 1, distributed over six slices in the north and south galactic caps. We have computed the power 1. 5 ] 80 spectrum P (k) for magnitude-limited samples of LCRS galaxies over wavelengths j \ 2n/k \ 5400 h~1 Mpc. The LCRS P (k) may be approximated as Pk~1. 8B0. 1 for small scales j \ 530 h~1 Mpc, changing to Pk1B1 for large scales j B 200400 h~1 Mpc. The overall amplitude corresponds to in p 8 \ 1. 0 ⁰. 1 redshift space.
