We present new and accurate measurements of the cosmic distance-redshift relation, spanning 0.2 10 Mpc/h considered in this analysis. The measured amplitudes then determine the cosmic distance D_V(z), which we obtain with 3-7% accuracies in six independent redshift slices, with the standard ruler originating in the known curvature of the model power spectrum at the smoothing scale. We introduce a new method for correcting the topological statistics for the sparse-sampling of the density field… Expand
Systematic Effects on the Genus Topology of the Large-scale Structure of the Universe
The large-scale structure of the universe is a useful cosmological probe of primordial non-Gaussianity and the expansion history of the universe because its topology does not change with time in theExpand
