We introduce a spatial averaging scheme and use it to study the evolution of spatial
averages in large-scale simulations of cosmological structure formation performed with the …

We apply and extend standard tools for void statistics to cosmological simulations that solve
Einstein's equations with numerical relativity (NR). We obtain a simulated void catalogue …

This review is an up-to-date account of the use of numerical relativity to study dynamical,
strong-gravity environments in a cosmological context. First, we provide a gentle introduction …

We propose a two parameters extension of the flat $\Lambda $ CDM model to capture the
impact of matter inhomogeneities on the background evolution of the Universe. Non …

In this study, we investigate the numerical stability of the covariant Baumgarte--Shapiro--
Shibata--Nakamura (cBSSN) formulation against the Friedmann--Lema\^ itre--Robertson …

In the quest for relativistic effects in large-scale structures, we use numerical relativity
simulations to describe the spacetime evolution during nonlinear structure formation. We …
