Geodesics for the Painleve-Gullstrand form of Lense-Thirring spacetime
Joshua Baines, Thomas Berry, Alex Simpson +1
Recently, the current authors have formulated and extensively explored a rather novel Painleve-Gullstrand variant of the slow-rotation Lense-Thirring spacetime, a variant which has…
Killing tensor and Carter constant for Painleve-Gullstrand form of Lense-Thirring spacetime
Joshua Baines, Thomas Berry, Alex Simpson +1
Recently, the authors have formulated and explored a novel Painleve-Gullstrand variant of the Lense-Thirring spacetime, which has some particularly elegant features -- including un…
Mimicking Black Holes in General Relativity
Thomas Berry
The central theme of this thesis is the study and analysis of black hole mimickers. The concept of a black hole mimicker is introduced, and various mimicker spacetime models are ex…
General class of "quantum deformed" regular black holes
Thomas Berry, Alex Simpson, Matt Visser
We discuss the "quantum deformed Schwarzschild spacetime" as originally introduced by Kazakov and Solodukhin in 1993, and investigate the precise sense in which it does and does no…
Lorentz boosts and Wigner rotations: self-adjoint complexified quaternions
Thomas Berry, Matt Visser
Herein we shall consider Lorentz boosts and Wigner rotations from a (complexified) quaternionic point of view. We shall demonstrate that for a suitably defined self-adjoint complex…
