GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
Coherent Gravitational Waveforms and Memory from Cosmic String Loops
Josu C. Aurrekoetxea, Thomas Helfer, Eugene A. Lim
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 re…
The Effects of Potential Shape on Inhomogeneous Inflation
Josu C. Aurrekoetxea, Katy Clough, Raphael Flauger +1
We study the robustness of single-field inflation against inhomogeneities. We derive a simple analytic criterion on the shape of the potential for successful inflation in the prese…
Cosmic String Loop Collapse in Full General Relativity
Thomas Helfer, Josu C. Aurrekoetxea, Eugene A. Lim
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…
