Relativistic Cosmological Simulations in Gravity I: Methodology
Lorenzo Reverberi, David Daverio
We present the new relativistic cosmological particle-mesh code , based on , aimed at simulating non-linear structure formation in …
General Relativistic Cosmological N-body Simulations I: time integration
David Daverio, Yves Dirian, Ermis Mitsou
This is the first in a series of papers devoted to fully general-relativistic -body simulations applied to late-time cosmology. The purpose of this paper is to present the combi…
Type I Abelian Higgs strings: evolution and Cosmic Microwave Background constraints
Mark Hindmarsh, Joanes Lizarraga, Jon Urrestilla +2
We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and Cosmic Microwave Background (CMB) con…
Safely smoothing spacetime: backreaction in relativistic cosmological simulations
Julian Adamek, Chris Clarkson, David Daverio +2
A persistent theme in the study of dark energy is the question of whether it really exists or not. It is often claimed hat we are mis-calculating the cosmological model by neglecti…
Scaling from gauge and scalar radiation in Abelian Higgs string networks
Mark Hindmarsh, Joanes Lizarraga, Jon Urrestilla +2
We investigate cosmic string networks in the Abelian Higgs model using data from a campaign of large-scale numerical simulations on lattices of up to grid points. We obser…
