Detecting the Beaming Effect of Gravitational Waves
Alejandro Torres-Orjuela, Xian Chen, Zhoujian Cao +2
The models currently used in the detection of gravitational waves (GWs) either do not consider a relative motion between the center-of-mass of the source and the observer, or usual…
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…
Relationship between Bondi-Sachs quantities and source of gravitational radiation in asymptotically de Sitter spacetime
Xiaokai He, Jiliang Jing, Zhoujian Cao
Gravitational radiation plays an important role in astrophysics. Based on the fact that our universe is expanding, the gravitational radiation when a positive cosmological constant…
