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…
The mass gap, the spin gap, and the origin of merging binary black holes
Vishal Baibhav, Davide Gerosa, Emanuele Berti +3
Two of the dominant channels to produce the black-hole binary mergers observed by LIGO and Virgo are believed to be the isolated evolution of stellar binaries in the field and dyna…
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…
Black hole formation in relativistic Oscillaton collisions
James Y. Widdicombe, Thomas Helfer, Eugene A. Lim
We investigate the physics of black hole formation from the head-on collisions of boosted equal mass Oscillatons (OS) in full numerical relativity, for both the cases where the OS…
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…
Formation of Relativistic Axion Stars
James Y. Widdicombe, Thomas Helfer, David J. E. Marsh +1
Axions and axion-like particles are compelling candidates for the missing dark matter of the universe. As they undergo gravitational collapse, they can form compact objects such as…
