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.
