Comparison of Analytical Mass Functions with Numerical Simulations
Jounghun Lee, Sergei F. Shandarin
We present numerical testing results of our mass function derived in our previous paper, and compare the testing results with those of the popular Press-Schechter (PS) mass functio…
Minkowski Functionals and Cluster Analysis for CMB Maps
D. Novikov, Hume A. Feldman, Sergei F. Shandarin
We suggest novel statistics for the CMB maps that are sensitive to non-Gaussian features. These statistics are natural generalizations of the geometrical and topological methods th…
Morphology of Clusters and Superclusters in N-body simulations of Cosmological Gravitational Clustering
B. S. Sathyaprakash, Varun Sahni, Sergei F. Shandarin
We analyse shapes of overdense regions (clusters and superclusters) in controlled N-body simulations of gravitational clustering with power law initial spectra P(k) \propto k^n, n…
Filaments and Pancakes in the IRAS 1.2 Jy Redshift Catalogue
B. S. Sathyaprakash, Varun Sahni, Sergei F. Shandarin +1
We explore shapes of clusters and superclusters in the IRAS 1.2 Jy redshift survey with three reconstructions spanning the range β= 0.1, 0.5, 1.0, where β= Ω^{0.6}/b, b is the bias…
The Large Scale Biasing and the Primordial Gravitational Potential
Jounghun Lee, Sergei F. Shandarin
We modified the Press-Schechter (PS) formalism and then analytically derived a constrained mass distribution function n(M|varphi) for the regions having some specified value of the…
Shapefinders: A new shape diagnostic for large scale structure
Varun Sahni, B. S. Sathyaprakash, Sergei F. Shandarin
We construct a set of shape-finders which determine shapes of compact surfaces (iso-density surfaces in galaxy surveys or N-body simulations) without fitting them to ellipsoidal co…
