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 …

We present DisPerSE, a novel approach to the coherent multiscale identification of all types
of astrophysical structures, in particular the filaments, in the large-scale distribution of the …

We review the field of collisionless numerical simulations for the large-scale structure of the
Universe. We start by providing the main set of equations solved by these simulations and …

The cosmic web is one of the most striking features of the distribution of galaxies and dark
matter on the largest scales in the Universe. It is composed of dense regions packed full of …

We explore voids in dark matter and halo fields from simulations of Λ cold dark matter and
Hu–Sawicki f (R) models. In f (R) gravity, dark matter void abundances are greater than that …

We present a purely geometrical method for probing the expansion history of the universe
from the observation of the shape of stacked voids in spectroscopic redshift surveys. Our …

In this paper, we propose a new dynamical classification of the cosmic web. Each point in
space is classified in one of four possible web types: voids, sheets, filaments and knots. The …

Do void statistics contain information beyond the tracer 2-point correlation function? Yes! As
we vary the sum of the neutrino masses, we find void statistics contain information absent …
