The Muenster Redshift Project. II. The Redshift Space Galaxy Power Spectrum

The redshift space galaxy power spectrum is estimated using magnitude- limited samples of up to 87,558 galaxies with redshifts z < 0.2 and magnitudes r_f_ <= 18.0 mag. Although the random redshift errors are comparatively large (σ_z_ = 0.031), the present survey sample gives reliable power spectral densities for wavenumbers 0.0125 <= k <= 0.15 h Mpc^-1^ corresponding to wavelengths 40 <= λ <= 500 h^-1^ Mpc. The Muenster Redshift Project data give a clear indication for the existence of a turnover in the shape of the power spectrum near wavelengths of 160 h^-1^ Mpc.
