Structure formation and quasi-spherical collapse from initial curvature perturbations with numerical relativity simulations
Robyn L. Munoz, Marco Bruni
We use numerical relativity simulations to describe the spacetime evolution during nonlinear structure formation in CDM cosmology. Fully nonlinear initial conditions are set at…
Bouncing cosmology from nonlinear dark energy with two cosmological constants
Molly Burkmar, Marco Bruni
We explore the dynamics of FLRW cosmologies which consist of dark matter, radiation and dark energy with a quadratic equation of state. Standard cosmological singularities arise du…
EBWeyl: a Code to Invariantly Characterize Numerical Spacetimes
Robyn L. Munoz, Marco Bruni
In order to invariantly characterise spacetimes resulting from cosmological simulations in numerical relativity, we present two different methodologies to compute the electric and…
Nonsingular Cosmology from an Interacting Vacuum
Marco Bruni, Rodrigo Maier, David Wands
We examine the dynamics of FLRW cosmologies in which the vacuum interacts with a perfect fluid through an energy exchange, focusing on the exploration of nonsingular configurations…
Shan--Chen interacting vacuum cosmology
Natalie B. Hogg, Marco Bruni
In this paper, we introduce a novel class of interacting vacuum models, based on recasting the equation of state originally developed in the context of lattice kinetic theory by Sh…
Vector modes in CDM: the gravitomagnetic potential in dark matter haloes from relativistic -body simulations
Cristian Barrera-Hinojosa, Baojiu Li, Marco Bruni +1
We investigate the transverse modes of the gravitational and velocity fields in CDM, based on a high-resolution simulation performed using the adaptive-mesh refinement general-r…
