Density field pscz

WebThe prime objective of this study is the production of optimal resolution three-dimensional maps of the volume-weighted velocity and density fields throughout the nearby Universe, the basis for a detailed study of the structure and dynamics of the cosmic web at each level probed by underlying galaxy sample. WebDec 21, 2004 · The PSC z survey's depth, excellent sky coverage and density allow for the reliable mapping of the distribution of galaxies in the Local Universe. Several independent determinations of the PSC z density and velocity fields have therefore been made, most notably by Branchini et al. (1999), Schmoldt et al. (1999) and Rowan-Robinson et al. …
