Journal ArticleDOI
Improved Cosmological Constraints from Gravitational Lens Statistics
TL;DR: In this paper, the authors combine the cosmic lens All-Sky Survey (CLASS) with new Sloan Digital Sky Survey (SDSS) data on the local velocity dispersion distribution function of E/S0 galaxies, to derive lens statistics constraints on the cosmological parameters.
Journal ArticleDOI
Voids in a $\Lambda$CDM Universe
TL;DR: In this paper, the formation and evolution of voids in the dark matter distribution using various simulations of the popular Lambda$ cold dark matter cosmogony is studied and a universal void mass profile is found.
Journal ArticleDOI
An excursion set model for the distribution of dark matter and dark matter haloes
TL;DR: In this paper, a model of the gravitationally evolved dark matter distribution in the Eulerian space is developed, which is a simple extension of the excursion set model that is commonly used to estimate the mass function of collapsed dark matter haloes.
Journal ArticleDOI
Redshift space correlations and scale-dependent stochastic biasing of density peaks
Vincent Desjacques,Ravi K. Sheth +1 more
TL;DR: In this article, the authors derived the power spectrum of density peaks of a Gaussian random field with peak bias and showed that the peak bias is stochastic and scale dependent, both in real and redshift space.
Journal ArticleDOI
The 2dF-SDSS LRG and QSO survey: evolution of the clustering of luminous red galaxies since z = 0.6

Drinkwater,Alastair C. Edge,Jon Loveday,Tsz Yan Lam,Kevin A. Pimbblet,Isaac Roseboom,Nicholas P. Ross,Donald P. Schneider,Tom Shanks,Rob Sharp +19 more
TL;DR: In this paper, the authors present an analysis of the small-to-intermediate scale clustering of samples of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey and the 2dF-SDSS LRG and QSO (2SLAQ) survey carefully matched to have the same rest-frame colours and luminosity.
