Universe: Large-Scale Structure, Cosmology

Scientific paper

The Minkowski functionals are a mathematical tool to quantify morphological features of patterns. Some applications to the matter distribution in galaxy catalogues and N-body simulations are reviewed, with an emphasis on the effects of cosmic variance. The conclusions are that (I) the observed large-scale morphology is sensitive to cosmic variance on scales much larger than the nonlinear length (≍8h-1Mpc), and (II) the large-scale morphology predicted by simulations is thus affected by finite-size effects, but nonetheless a ΛCDM model is favored.
