The effect of wave dark matter on equal mass black hole mergers
Josu C. Aurrekoetxea, Katy Clough, Jamie Bamber +1
For dark matter to be detectable with gravitational waves from binary black holes, it must reach higher than average densities in their vicinity. In the case of light (wave-like) d…
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…
GRFolres: A code for modified gravity simulations in strong gravity
Llibert Aresté Saló, Sam E. Brady, Katy Clough +6
GRFolres is an open-source code for performing simulations in modified theories of gravity, based on the publicly available 3+1D numerical relativity code GRChombo. Note: Submitted…
GRDzhadzha: A code for evolving relativistic matter on analytic metric backgrounds
Josu C. Aurrekoetxea, Jamie Bamber, Sam E. Brady +5
GRDzhadzha is an open-source code for relativistic simulations of matter fields on curved spacetimes that admit an analytic description (e.g. stationary black holes). It is based o…
Solving the initial conditions problem for modified gravity theories
Sam E. Brady, Llibert Aresté Saló, Katy Clough +2
Modified gravity theories such as Einstein scalar Gauss Bonnet (EsGB) contain higher derivative terms in the spacetime curvature in their action, which results in modifications to…
Tunnelling-induced cosmic bounce in the presence of anisotropies
Jean Alexandre, Katy Clough, Silvia Pla
If we imagine rewinding the universe to early times, the scale factor shrinks and the existence of a finite spatial volume may play a role in quantum tunnelling effects in a closed…
Testing the limits of scalar-Gauss-Bonnet gravity through nonlinear evolutions of spin-induced scalarization
Daniela D. Doneva, Llibert Aresté Saló, Katy Clough +2
Quadratic theories of gravity with second order equations of motion provide an interesting model for testing deviations from general relativity in the strong gravity regime. Howeve…
Puncture gauge formulation for Einstein-Gauss-Bonnet gravity and four-derivative scalar-tensor theories in spacetime dimensions
Llibert Aresté Saló, Katy Clough, Pau Figueras
We develop a modified CCZ4 formulation of the Einstein equations in spacetime dimensions for general relativity plus a Gauss-Bonnet term, as well as for the most general pari…
Relativistic drag forces on black holes from scalar dark matter clouds of all sizes
Dina Traykova, Rodrigo Vicente, Katy Clough +4
We use numerical simulations of scalar field dark matter evolving on a moving black hole background to confirm the regime of validity of (semi-)analytic expressions derived from fi…
Oscillon formation during inflationary preheating with general relativity
Josu C. Aurrekoetxea, Katy Clough, Francesco Muia
We study the non-perturbative evolution of inflationary fluctuations during preheating using fully non-linear general-relativistic field-theory simulations. We choose a single-fiel…
