摘要：

We use the Center for Astrophysics Redshift Survey, now complete to m(B) less-than-or-equal-to 15.5 over eleven 6-degrees slices, to measure the power spectrum of the galaxy distribution up to wavelengths approximately 200 h-1 Mpc. The combination of large spatial and angular extent with high sampling density allows simultaneous measurement of the power spectrum on both large and small scales. Comparison with large (L greater-than-or-similar-to 400 h-1 Mpc) N-body simulations of cosmological models shows that the power spectrum of the standard CDM model (OMEGA-h = 0.5 and sigma(8) = 1; see below for definitions) is inconsistent with the observed power spectrum at the 99% confidence level. The power spectrum of an open CDM model (OMEGA-h = 0.2 and sigma(8) = 1) best approximates the observed power spectrum for wavelengths < 125 h-1 Mpc.
