Optical Appearance of a Rotating Black Hole in Nonlinear Electrodynamics Surrounded by Thin Accretion Disks
Abdul Malik Sultan, Manahil Ali, Muhammad Israr Aslam +1
This work investigates the optical appearance of a rotating black hole (BH) in nonlinear electrodynamics (NED) using two illumination models, namely a celestial sphere and a thin a…
Optical appearance of Einstein-Æther black hole surrounded by thin disk
Hui-Min Wang, Zi-Chao Lin, Shao-Wen Wei
In Einstein-Æther theory, the Lorentz symmetry is locally broken in the high-energy regime due to the presence of theÆther field. This shall leave significant imprint on astronomic…
Shortcut in codimension-2 brane cosmology in light of GW170817
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu
In this paper, our universe is regarded as a codimension-2 brane embedded in a noncompact six-dimensional Anti-de Sitter (AdS) spacetime. We derive the gravitational horizon radius…
Equivalence of solutions between the four-dimensional novel and regularized EGB theories in a cylindrically symmetric spacetime
Zi-Chao Lin, Ke Yang, Shao-Wen Wei +2
Recently, a novel four-dimensional Einstein-Gauss-Bonnet (EGB) theory was presented to bypass the Lovelock's theorem and to give nontrivial effects on the four-dimensional local gr…
Constraint on the radius of five-dimensional dS spacetime with GW170817 and GRB 170817A
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu
The recent detections of the gravitational wave (GW) event GW170817 and its electromagnetic counterpart GRB 170817A produced by a binary neutron star (NS) merger is a new milestone…
Gravitational waves and extra dimensions: a short review
Hao Yu, Zi-Chao Lin, Yu-Xiao Liu
We give a brief review on the recent development of gravitational waves in extra-dimensional theories of gravity. Studying extra-dimensional theories with gravitational waves provi…
