Axial Gravitational Normal Modes of Uniform Density Star in Anti-de Sitter Spacetime
Kai Lin, Alan B. Pavan, Amilcar Rabelo de Queiroz +1
The article studies the dynamical behavior of axial gravitational perturbations of homogeneous stars in Anti-de Sitter spacetime. Because the radial coordinate transforms into…

Finitely supertranslated Schwarzschild black hole and its perturbations
Shaoqi Hou, Kai Lin, Zong-Hong Zhu
A finitely supertranslated Schwarzschild black hole possesses nontrivial super-Lorentz charges compared with the standard one. This may impact the quasinormal modes of the black ho…
