Gravitational waves from eccentric extreme mass-ratio inspirals as probes of scalar fields

C Zhang, Y Gong, D Liang, B Wang - Journal of Cosmology and …, 2023 - iopscience.iop.org
We study eccentric orbits of the Schwarzschild spacetime for extreme mass ratio system
(EMRI) in modified gravity theories with additional scalar fields. Due to the additional energy …

Probing Quantum Gravity Effects with Eccentric Extreme Mass-Ratio Inspirals

G Fu, Y Liu, B Wang, JP Wu, C Zhang - arXiv preprint arXiv:2409.08138, 2024 - arxiv.org
In this paper, we investigate the impact of loop quantum gravity (LQG) on extreme mass-ratio
inspirals (EMRIs), and the results indicate that LQG effects cause the orbital decay to occur …

Gravitational odd-parity perturbation of a Horndeski hairy black hole: quasinormal mode and parameter constraint

ZH Yang, YH Lei, XM Kuang, B Wang - The European Physical Journal C, 2025 - Springer
During the binary black hole coalescence, gravitational waves emitted at the ringdown stage
can be well described by black hole perturbation theory, where the quasinormal modes …

Gravitational waves from equatorially eccentric extreme mass ratio inspirals around swirling Kerr black holes

Testing general relativity with gravitational waves from extreme mass-ratio inspirals

S Barsanti - 2024 - iris.uniroma1.it
Abstract Extreme Mass Ratio Inspirals (EMRIs) are asymmetric binary systems. They are
composed of a massive black hole and a stellar mass compact object, which inspirals until …
