Binary black hole simulation with an adaptive finite element method II: Application of local discontinuous Galerkin method to Einstein equations
Zhoujian Cao, Pei Fu, Li-Wei Ji +1
Finite difference method and pseudo-spectral method have been widely used in the numerical relativity to solve the Einstein equations. As the third major category method to solve p…
Binary black hole simulation with an adaptive finite element method III: Evolving a single black hole
Li-Wei Ji, Rong-Gen Cai, Zhoujian Cao
We extend a new finite element code, Einstein PHG (iPHG), to solve the evolution part of Einstein equations in first-order GH formalism. This paper is the third one of a systematic…
An axion-like scalar field environment effect on binary black hole merger
Qing Yang, Li-Wei Ji, Bin Hu +2
Environment, such as the accretion disk, could modify the signal of the gravitational wave from the astrophysical black hole binaries. In this article, we model the matter field ar…
On the critical behaviour of gapped gravitational collapse in confined spacetime
Rong-Gen Cai, Li-Wei Ji, Run-Qiu Yang
The gravitational collapse of a massless scalar field enclosed with a perfectly reflecting wall in a spacetime with a cosmological constant is investigated. The mass scaling fo…
Collapse of self-interacting scalar field in anti-de Sitter space
Rong-Gen Cai, Li-Wei Ji, Run-Qiu Yang
The gravitational collapse of a massless scalar field with a self-interaction term in anti-de Sitter space is investigated. We numerically investigate the effect of the self…
