Journal ArticleDOI
Halo Models of Large Scale Structure
TL;DR: In this paper, the authors review the formalism and applications of the halo-based description of non-linear gravitational clustering, and demonstrate its accuracy by comparing its predictions with exact results from numerical simulations of nonlinear gravity clustering.
Journal ArticleDOI
Ellipsoidal collapse and an improved model for the number and spatial distribution of dark matter haloes
TL;DR: In this article, the authors show that the discrepancy between theory and simulation can be reduced substantially if bound structures are assumed to form from an ellipsoidal, rather than a spherical, collapse.
Journal ArticleDOI
An excursion set model of hierarchical clustering: ellipsoidal collapse and the moving barrier
Ravi K. Sheth,Giuseppe Tormen +1 more
TL;DR: In this article, the authors compare the excursion set predictions associated with spherical and ellipsoidal collapse and show that the spherical collapse-based moving barrier model provides a better description of what we measure in the numerical simulations than the spherical collapsing-based constant barrier model, although the agreement between model and simulations is better at large lookback times.
Journal ArticleDOI
A hierarchy of voids: much ado about nothing
TL;DR: In this article, the authors present a model for the distribution of void sizes and its evolution in the context of hierarchical scenarios of gravitational structure formation, and show that at any cosmic epoch the voids have a size distribution that is well-peaked about a characteristic void size that evolves self-similarly in time.
Journal ArticleDOI
Large-scale galaxy bias
TL;DR: In this paper, the authors present a comprehensive overview of galaxy bias, that is, the statistical relation between the distribution of galaxies and matter, which forms the basis of the rigorous perturbative description of galaxy clustering, under the assumptions of General Relativity and Gaussian, adiabatic initial conditions.
