Angular velocity of rotating black holes -- a new way to construct initial data for binary black holes
Shuanglin Huang, Xuefeng Feng, Yun-Kau Lau
Motivated by a geometric understanding of the angular velocity of a Kerr black hole in terms of a quasi-conformal map that describes a 2d Beltrami fluid flow, a new way to construc…
Adaptive extended Kalman filter and laser link acquisition in the detection of gravitational waves in space
Jinke Yang, Yong Xie, Yidi Fan +8
An alternative, new laser link acquisition scheme for the triangular constellation of spacecraft (SCs) in deep space in the detection of gravitational waves is considered. In place…
Geometric Inequality for Axisymmetric Black Holes With Angular Momentum
Xuefeng Feng, Ruodi Yan, Sijie Gao +2
In an effort to understand the Penrose inequality for black holes with angular momentum, an axisymmetric, vacuum, asymptotically Euclidean initial data set subject to certain quasi…
Resonant Scattering of Gravitational Waves With Electromagnetic Waves
Ruodi Yan, Yun Kau Lau
A certain class of exact solutions of Einstein Maxwell spacetime in general relativity is discussed which demonstrates at the level of theory that, when certain parametric resonanc…
