Periodic orbits and gravitational waveforms of black holes in bumblebee gravity
Zijian Shi, Xiangdong Zhang, Yunlong Liu
In this paper, we investigate the dynamics of massive particles and the associated gravitational waveforms in the spacetime of a black hole within the framework of Einstein-Bumbleb…
Periodic orbits and gravitational waveforms of spinning particles in nonlocal Gravity
Moisés Bravo-Gaete, Jianhui Lin, Yunlong Liu +1
In this paper, we investigate the dynamics and gravitational-wave signatures of periodic orbits of spinning test particles moving in the equatorial plane around static, spherically…
Solar-system experimental constraints on nonlocal gravity
Yunlong Liu, Yongbin Du
In this work, we study the constraints on the characteristic parameters of the Deser-Woodard nonlocal gravity model in a static and spherically symmetric background, using…
Quasinormal modes and tidal Love numbers of covariant effective quantum black holes with cosmological constant
Yunlong Liu, Xiangdong Zhang
This paper systematically investigates the quasinormal modes (QNMs) and tidal Love numbers of covariant quantum-modified black holes (BHs) within two cosmological constant-dependen…
Spinning Particle Dynamics and ISCO in Covariant Loop Quantum Gravity
Yongbin Du, Yunlong Liu, Xiangdong Zhang
In this paper, we investigate the motion of spinning particles in the background of covariant loop quantum gravity black holes, focusing on two distinct effective metric solutions.…
