Efficient and Stable Computation of Gravitational-Wave Fluxes from Generic Kerr Orbits via a Unified HeunC Framework

Changkai Chen, Zhoujian Cao, Jiliang Jing

Modeling extreme-mass-ratio inspirals hinges on the accurate and efficient computation of gravitational-wave fluxes from generic Kerr orbits. Conventional frequency-domain techniqu…

Constraining Kerr supermassive black hole properties using gravitational waves from inspiraling stellar-mass binary black holes

Jie Wu, Jin-Tao Yao, Mengfei Sun +2

We study the capability of future space-based gravitational-wave (GW) detectors to constrain supermassive black hole (SMBH) properties through observations of inspiraling stellar-m…

Large-Eccentricity Asymptotics and Fast Analytic Approximation for Fourier modes of Post-Newtonian Eccentric Waveforms

Xiaolin Liu, Zhoujian Cao

In this work, we developed analytic asymptotic methods for computing the Fourier modes of gravitational waves from post-Newtonian binary systems in the quasi-Keplerian parametrizat…

A Dynamical Equilibrium Linking Nanohertz Stochastic Gravitational Wave Background to Cosmic Structure Formation

Manjia Liang, Peng Xu, Ruijun Shi +6

The stochastic gravitational wave background (SGWB) is conventionally treated as a passive relic of its astrophysical and cosmological sources, with negligible back-reaction on the…

General Fourier expansion of post-Newtonian binary dynamics based on a quasi-Keplerian framework

Xiaolin Liu, Zhoujian Cao

We have introduced a new method for computing gravitational-wave emission from nonspinning binaries which systematically unifies the various integrals arising in the Fourier expans…

Space-borne Interferometers to Detect Thousands of Memory Signals Emitted by Stellar-mass Binary Black Holes

Shaoqi Hou, Zhi-Chao Zhao, Zhoujian Cao +1

The gravitational memory effect manifests gravitational nonlinearity, degenerate vacua, and asymptotic symmetries; its detection is considered challenging. We propose using the spa…
