We study the structure and substructure of halos obtained in N-body simulations for a ΛCDM cosmology with non-Gaussian initial conditions. The initial statistics are lognormal in the gravitational potential field with positive (LNp) and negative (LNn) skewness; the sign of the skewness is conserved by the density field, and the power spectrum is the same for all the simulations. Our aim is not to test a given non-Gaussian statistics but to explore the generic effect of positive- and negative…

Cosmic shear statistics in cosmologies with non-Gaussian initial conditions
We computed the power spectrum of weak cosmic shear in models with non-Gaussian primordial density fluctuations. Cosmological initial condit ions deviating from Gaussianity have recently attracted
The effects of primordial non-Gaussianity on giant-arc statistics
For over a decade, it has been debated whether the concordance A cold dark matter (ACDM) model is consistent with the observed abundance of giant arcs in clusters. While previous theoretical studies

We studied the effect of primordial non-Gaussianity with varied bispectrum shapes on the number counts of signal-to-noise ratio peaks in wide-field cosmic shear maps. The two cosmological

We address whether possible scale-dependent deviations from Gaussianity in the primordial density field that are consistent with the cosmic microwave background observations could explain the
Power spectrum normalization and the non‐Gaussian halo model
The normalization of the matter power spectrum, σ 8 , is an essential ingredient to predict the phenomenology of the low-redshift Universe. It has been measured using several methods, such as X-ray

Projection effects in the strong lensing study of subhaloes
The defining characteristic of the cold dark matter (CDM) hypothesis is the presence of a very large number of low-mass haloes, too small to have made a visible galaxy. Other hypotheses for the

We examine the cosmological constraining power of future large-scale weak lensing surveys on the model of the ESA planned mission Euclid, with particular reference to primordial non-Gaussianity. Our
