Gravitational radiations from periodic orbits around a black hole in the effective field theory extension of general relativity
Shuo Lu, Hao-Jie Lin, Tao Zhu +2
The study of periodic orbits in extreme-mass-ratio inspirals is essential for understanding the dynamics of small bodies orbiting supermassive black holes. In this paper, we study…
Fundamental Physics and Cosmology with TianQin
Jun Luo, Haipeng An, Ligong Bian +33
The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this g…
A Universal Framework for Horizon-Scale Tests of Gravity with Black Hole Shadows
Wentao Liu, Yang Liu, Di Wu +1
In this Letter, we have developed a numerically efficient framework for evaluating parameters in metric theories of gravity, and applied it to constrain the horizon-scale magnetic…
Explicit and covariant formula for thermodynamic volume in extended black hole thermodynamics
Yong Xiao, Yu-Xiao Liu, Yu Tian +1
In extended black hole thermodynamics, the cosmological constant and other couplings are treated as thermodynamic variables, yielding the first law $\tildeδM = T\tildeδS+Ω\tilde…
Gravitational Wave Detection Based on Gravitomagnetic Effects
Yu-Qi Dong, Zhoujian Cao, Yu-Xiao Liu
In this paper, we explore the feasibility of detecting gravitomagnetic effects generated by gravitational waves, by monitoring the relative orientation of the angular momentum vect…
Gravitational wave cosmology
Ligong Bian, Rong-Gen Cai, Yu-Qi Dong +18
Gravitational waves (GWs) originating from cosmological sources offer direct insights into the physics of the primordial Universe, the fundamental nature of gravity, and the cosmic…
