Unequal-mass boson-star binaries: Initial data and merger dynamics
Tamara Evstafyeva, Ulrich Sperhake, Thomas Helfer +4
We present a generalization of the curative initial data construction derived for equal-mass compact binaries in Helfer {\it et al} (2019 Phys. Rev. D 99 044046; 2022 Class. Quantu…
The Gravitational Afterglow of Boson Stars
Robin Croft, Thomas Helfer, Bo-Xuan Ge +5
In this work we study the long-lived post-merger gravitational wave signature of a boson-star binary coalescence. We use full numerical relativity to simulate the post-merger and t…
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…
