Conformal Killing--Yano Ricci solitons: Structure, compatibility, and rigidity
Mohammadjavad Habibivostakolaei, Abbas M. Sherif, Yen-Kheng Lim
We introduce a geometric structure -- a conformal Killing--Yano Ricci soliton (CKY--RS) -- that couples conformal Ricci soliton (CRS) geometry to conformal Killing--Yano (CKY) 2--f…
Probing the Strong Equivalence Principle through the External Field Effect. How Do Two Masses Fall?
Ankit Kumar, Kelvin Tang Tee Tniam, Peng Chengxiaohe +5
Despite compelling evidence, the absence of a confirmed dark matter particle has sustained interest in modified gravity as an alternative explanation for the observed phenomenology…
Magnetising de Sitter and Anti-de Sitter spacetimes
Yun-Ten Chin, Yen-Kheng Lim
We attempt to magnetise the de Sitter (dS) and Anti-de Sitter (AdS) spacetimes in spherical symmetry. First, the weak field case is considered where Maxwell's equation is solved to…
Interior marginally outer trapped surfaces in Hayward black holes
Abbas M. Sherif, Yen-Kheng Lim
We locate interior marginally outer trapped and marginally outer trapped open surfaces (MOTS/MOTOS) in the regular Haward metric with parameter for which a critical (extremal)…
Weyl-type solutions with multipolar scalar fields
Yen-Kheng Lim
A class of solutions in -dimensional Einstein gravity minimally coupled to a massless scalar field is studied, where the spacetime metric is of a generalized Weyl form with $d-2…
Properties of the magnetic universe with positive cosmological constant
Yu-Xuan Toh, Yun-Ten Chin, Ethan Quanrun Wu +1
The properties of the Melvin-type spacetime with a positive cosmological constant in -dimensional Einstein--Maxwell gravity is studied. The solution is parametrised in terms…
Periodic orbits of neutral test particles in Reissner-Nordström naked singularities
Zoe C S Chan, Yen-Kheng Lim
We conduct studies on Levin's taxonomy of periodic orbits for neutral test particles around a Reissner-Nordström naked singularity. It was known that naked singularities could harb…
Energies and angular momenta of periodic Schwarzschild geodesics
Yen-Kheng Lim, Zhi Cheng Yeo
We consider physical parameters of Levin and Perez-Giz's `periodic table of orbits' around the Schwarzschild black hole, where each periodic orbit is classified according to three…
