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…
Spinning primordial black holes formed during a matter-dominated era
Eloy de Jong, Josu C. Aurrekoetxea, Eugene A. Lim +1
We study the formation of spinning primordial black holes during an early matter-dominated era. Using non-linear 3+1D general relativistic simulations, we compute the efficiency of…
Modelling self-consistently beyond General Relativity
Ramiro Cayuso, Pau Figueras, Tiago França +1
The majority of extensions to General Relativity display mathematical pathologies (higher derivatives, character change in equations that can be classified within PDE theory, and e…
The endpoint of the Gregory-Laflamme instability of black strings revisited
Pau Figueras, Tiago França, Chenxia Gu +1
We reproduce and extend the previous studies of Lehner and Pretorius of the endpoint of the Gregory-Laflamme instability of black strings in five space-time dimensions. We consider…
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…
Black Hole Binaries in Cubic Horndeski Theories
Pau Figueras, Tiago França
We study black hole binary mergers in certain cubic Horndeski theories of gravity, treating them fully non-linearly. In the regime of validity of effective field theory, the mismat…
Lessons for adaptive mesh refinement in numerical relativity
Miren Radia, Ulrich Sperhake, Amelia Drew +7
We demonstrate the flexibility and utility of the Berger-Rigoutsos Adaptive Mesh Refinement (AMR) algorithm used in the open-source numerical relativity code GRChombo for generatin…
Gravitational Collapse in Cubic Horndeski Theories
Pau Figueras, Tiago França
We study spherically symmetric gravitational collapse in cubic Horndeski theories of gravity. By varying the coupling constants and the initial amplitude of the scalar field, we de…
