Luminous matter produces very energetic events, such as active galactic nuclei and
supernova explosions, that significantly affect the internal regions of galaxy clusters …

We consider the recently proposed possibility that dark energy (DE) and baryons may
scatter through a pure momentum exchange process, leaving the background evolution …

We review dark energy models that can present non-negligible fluctuations on scales
smaller than Hubble radius. Both linear and nonlinear evolutions of dark energy fluctuations …

Galaxy-galaxy strong gravitational lenses have become a popular probe of dark matter (DM)
by providing a window into structure formation on the smallest scales. In particular, the …

Observational cosmology is passing through a unique moment of grandeur with the amount
of quality data growing fast. However, in order to better take advantage of this moment, data …

N-body cosmological simulations are an essential tool to understand the observed
distribution of galaxies. We use the MultiDark simulation suite, run with the Planck …

Aims. The main goal of this paper is to derive observational constraints on the halo mass
fuction (HMF) by performing a tomographic analysis of the magnification bias signal on a …

Aims. The main purpose of this work is to provide a proof-of-concept method to derive
tabulated observational constraints on the halo mass function (HMF) by studying the …

The discrepancy between the weak lensing (WL) and the Planck measurements of S 8 has
been a subject of several studies. Assuming that residual systematics are not the cause …

Within the standard paradigm, dark energy is taken as a homogeneous fluid that drives the
accelerated expansion of the universe and does not contribute to the mass of collapsed …
