A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

This review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …

Weak galaxy lensing surveys have consistently reported a lower amplitude for the matter
fluctuation spectrum, as measured by the S 8 parameter, than expected in the ΛCDM …

Within the Lambda cold dark matter (ΛCDM) model, measurements from recent cosmic
microwave background (CMB) and weak lensing (WL) surveys have uncovered a∼ 3σ …

Aims. The Euclid space telescope will measure the shapes and redshifts of galaxies to
reconstruct the expansion history of the Universe and the growth of cosmic structures. The …

Despite its continued observational successes, there is a persistent (and growing) interest in
extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of …

Aims: The Euclid space telescope will measure the shapes and redshifts of galaxies to
reconstruct the expansion history of the Universe and the growth of cosmic structures. The …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2020 within the cosmic vision 2015–2025 program. The main goal of Euclid is to understand …

Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound
overdensities in the initial density field and is accompanied by the most energetic …

We use a suite of cosmological simulations to study the mass–concentration–redshift
relation, c (M, z), of dark matter haloes. Our simulations include standard Λ-cold dark matter …
