Void Statistics and Hierarchical Scaling in the Halo Model
J. N. Fry, S. Colombi
We study scaling behaviour of statistics of voids in the context of the halo model of nonlinear large-scale structure. The halo model allows us to understand why the observed galax…
Using Local Volume data to constrain Dark Matter dynamics
G. Lavaux, R. Mohayaee, S. Colombi +1
The peculiar velocity reconstruction methods allow one to have a deeper insight into the distribution of dark matter: both to measure mean matter density and to obtain the primordi…
Large-Scale Structure of the Universe and Cosmological Perturbation Theory
F. Bernardeau, S. Colombi, E. Gaztanaga +1
We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravita…
Weak Lensing Predictions at Intermediate Scales
L. Van Waerbeke, T. Hamana, R. Scoccimarro +2
As pointed out in previous studies, the measurement of the skewness of the convergence field will be useful in breaking the degeneracy among the cosmological parameters constra…
Redshift Distortions of Clustering: A Lagrangian Approach
E. Hivon, F. R. Bouchet, S. Colombi +1
We study the effects of peculiar velocities on statistical measures of galaxy clustering. These effects occur when distances to the galaxies are estimated from their redshifts. It…
Skewness Induced by Gravity
R. Juszkiewicz, F. R. Bouchet, S. Colombi
Large-scale structures, observed today, are generally believed to have grown from random, small-amplitude inhomogeneities, present in the early Universe. We investigate how gravita…
