Black Spaghetti: A Numerical Model of Gravitational Collapse in 4 + 1 Spacetime
… ideas concerning hypothetical objects called "black strings," or black holes extending into an extra circular dimension, which dimension we hereinafter label zeta. These putative objects were first seriously considered as elements of string theory but have relevance in simpler, …

Heterotic Braneworld Gravity
… LOSW model, and explore the possibilities for a black hole solution. Using perturbation theory, we find that the zero mode sector consists of the graviton and the radion which is coupled to the bulk scalar field, and there is a continuum of massive states. The brane gravity is scalar-tensor with …

Black holes and solitons in string theory and M-theory: a low energy limit analysis
… and higher-curvature corrections from superstring theory on black hole and soliton physics in different dimensions. The first order α ′−corrections derived from heterotic string theory, up to a field redefinition, lead to Einstein-dilaton-Gauss-Bonnet theory. We construct the first-order …

Asmptotically Plane Wave Spacetimes
… waves, variational principles for gravity and black holes in higher dimensions. We then propose a definition of asymptotically plane wave spacetimes in vacuum gravity in terms of the asymptotic fall-off of the metric and discuss the relation to previously constructed exact solutions. We …

Applications of Numerical Relativity Beyond Astrophysics
… success in simulating the merger of binary black hole systems. Gravitational waveforms resulting from these simulations serve as precise theoretical predictions of general relativity, which can be tested against observational data, such as those recently made by the LIGO experiment. This …

The Gregory--Laflamme Instability and Conservation Laws for Linearised Gravity
This thesis is concerned with the black hole stability problem in general relativity. In particular, it presents stability and instability results associated to the linearised vacuum Einstein equation on black hole backgrounds. The first chapter of this thesis gives a direct rigorous mathematical …
