GRTresna: An open-source code to solve the initial data constraints in numerical relativity
Josu C. Aurrekoetxea, Sam E. Brady, Llibert Aresté-Saló +11
GRTresna is a multigrid solver designed to solve the constraint equations for the initial data required in numerical relativity simulations. In particular, it is focussed on scenar…
Hair is complicated: Gravitational waves from stable and unstable boson-star mergers
Bo-Xuan Ge, Eugene A. Lim, Ulrich Sperhake +5
We explore the gravitational-wave emission from head-on collisions of equal-mass solitonic boson-star binaries from simulations spanning a two-dimensional parameter space, consisti…
Cosmology using numerical relativity
Josu C. Aurrekoetxea, Katy Clough, Eugene A. Lim
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 introd…
Robustness of inflation to kinetic inhomogeneities
Matthew Elley, Josu C. Aurrekoetxea, Katy Clough +3
We investigate the effects of large inhomogeneities in both the inflaton field and its momentum. We find that in general, large kinetic perturbations reduce the number of e-folds o…
Multimessenger signals from compact axion star mergers
Liina Chung-Jukko, Eugene A. Lim, David J. E. Marsh
Axion dark matter can form stable, self-gravitating, and coherent configurations known as axion stars, which are rendered unstable above a critical mass by the Chern-Simons couplin…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
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…
