Characteristic precessions of spherical orbit around a rotating braneworld black hole
Hui-Min Wang, Kai Liao, Shao-Wen Wei
We study the orbital dynamics and relativistic precession effects in the spacetime of rotating braneworld black holes within the Randall-Sundrum framework. For test particles on sp…

Time Delay Anomalies of Fuzzy Gravitational Lenses
Jianxiang Liu, Zijun Gao, Marek Biesiada +1
Fuzzy dark matter is a promising alternative to the standard cold dark matter. It has quite recently been noticed, that they can not only successfully explain the large-scale struc…

A robust test of general relativity at the galactic scales by combining strong lensing systems and gravitational wave standard sirens
Tonghua Liu, Marek Biesiada, Shuxun Tian +1
The measurement of the parametrized post-Newtonian parameter is a robust test of general relativity (GR). In some modified theories of gravity, may ev…
