Probing vector hair of black holes with extreme mass ratio inspirals
Dicong Liang, Rui Xu, Zhan-Feng Mai +1
The bumblebee gravity model, with a vector field nonminimally coupled to gravity, is a natural extension of the Einstein-Maxwell theory. In this theory, a black hole can carry a ve…
Gravitational waves from eccentric extreme mass-ratio inspirals as probes of scalar fields
Chao Zhang, Yungui Gong, Dicong Liang +1
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 ener…
Static spherical vacuum solutions in the bumblebee gravity model
Rui Xu, Dicong Liang, Lijing Shao
The bumblebee gravity model is a vector-tensor theory of gravitation where the vector field nonminimally couples to the Ricci tensor. By investigating the vacuum field equations wi…
Polarizations of Gravitational Waves in the Bumblebee Gravity Model
Dicong Liang, Rui Xu, Xuchen Lu +1
Lorentz violation modifies the dispersion relation of gravitational waves (GWs), and induces birefringence and anisotropy in propagation. Our study shows that Lorentz violation can…
