  journal={Physical Review D},
We implement adaptive mesh refinement (AMR) simulations of global topological strings using the public code, GRChombo. We perform a quantitative investigation of massive radiation from single sinusoidally displaced string configurations, studying a range of string widths defined by the coupling parameter $\lambda$ over two orders of magnitude, effectively varying the mass of radiated particles $m_H \sim \sqrt{\lambda}$. We perform an in-depth investigation into the effects of AMR on massive… 



Lessons for adaptive mesh refinement in numerical relativity

We demonstrate the flexibility and utility of the Berger–Rigoutsos adaptive mesh refinement (AMR) algorithm used in the open-source numerical relativity (NR) code GRChombo for generating

Dark matter from axion strings with adaptive mesh refinement

Axions are hypothetical particles that may explain the observed dark matter density and the non-observation of a neutron electric dipole moment. An increasing number of axion laboratory searches are

Cosmic string loop collapse in full general relativity

We present the first fully general relativistic dynamical simulations of Abelian-Higgs cosmic strings using 3+1D numerical relativity. Focusing on cosmic string loops, we show that they collapse due

Radiative back reaction on global strings.

It is established that the `local backreaction approximation' provides a satisfactory quantitative description of radiative damping for a wide variety of string configurations.

Decay of cosmic global string loops

We numerically study the decay of cosmic global string loops due to radiation of Goldstone bosons and massive scalar ($\chi$) particles. The length of loops we study range from 200-1000 times the

Where is the ringdown: Reconstructing quasinormal modes from dispersive waves

We study the generation and propagation of gravitational waves in scalar-tensor gravity using numerical relativity simulations of scalar field collapses beyond spherical symmetry. This allows us to

Coherent gravitational waveforms and memory from cosmic string loops

We construct, for the first time, the time-domain gravitational wave strain waveform from the collapse of a strongly gravitating Abelian Higgs cosmic string loop in full general relativity. We show

Multi-messenger constraints on Abelian-Higgs cosmic string networks

Nielsen-Olesen vortices in the Abelian-Higgs (AH) model are the simplest realisations of cosmic strings in a gauge field theory. Large-scale numerical solutions show that the dominant decay channel

A window for cosmic strings

Particle emission, in addition to gravitational radiation from cosmic string loops, affects the resulting loop distribution and hence the corresponding observational consequences of cosmic strings.

On the Evolution of Abelian-Higgs String Networks

We study the evolution of Abelian-Higgs string networks in large-scale numerical simulations in both a static and expanding background. We measure the properties of the network by tracing the motion
