Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…
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…
Relativistic excitation of compact stars
Zhiqiang Miao, Xuefeng Feng, Zhen Pan +1
In this work, we study the excitation of a compact star under the influence of external gravitational driving in the relativistic regime. Using a model setup in which a wave with c…
Universal gravitational self-force for a point mass orbiting around a compact star
Xuefeng Feng, Huan Yang
In this work, we study the gravitational back-reaction (i.e., the "self-force") of a point mass moving around a non-rotating, compact star on a circular orbit. We find that the add…
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…
