Traversable Wormholes in Kerr Black Holes
Wormholes have long been a source of interest in general relativity, having been first coined by John Wheeler in 1957. More recently, wormholes have proven instrumental to our understanding of quantum gravity, with particular interest being given to Euclidean wormholes and their relevance to the …

Radiation transport around Kerr black holes
… code for analyzing accretion processes around Kerr black holes. We begin in Chapter 1 with a brief historical summary of the major advances in black hole astrophysics over the past few decades. In Chapter 2 we present a detailed description of the ray-tracing code, which can be used to …

Gravitational Waves From Perturbed Kerr Black Holes: Two Investigations
… The first project is a study of the effect of black hole spin on the accuracy of the post-Newtonian approximation. We focus on the gravitational energy produced by the quasicircular, equatorial, extreme mass-ratio inspiral of a compact object into a Kerr black hole of mass M and spin J. For a …

The imprint of scalar clouds around Kerr black holes: hairy solutions and weak cosmic censorship
… matter, and more specifically, we focus on the Kerr black hole in the presence of a massive scalar field. We investigate the superradiant phenomenon present in this setting - amplified scattering of scalar waves by the black hole given the right conditions on the scalar field's frequency are …

Gravitomagnetic effects in compact binary systems : a study of spin-enhanced orbits around Kerr black holes
… spin-induced evolution of inclined, eccentric Kerr black hole orbits. The evolution of the orbital energy, angular momentum, and Carter constant for such orbits is driven by the local spin force on the orbiting body, which is inferred from the Papapetrou equations. We find that the variation of …

Computing and analyzing gravitational radiation in black hole simulations using a new multi-block approach to numerical relativity
Numerical simulations of Kerr black holes are presented and the excitation of quasinormal modes is studied in detail. Issues concerning the extraction of gravitational waves from numerical space-times and analyzing them in a systematic way are discussed. A new multi-block infrastructure for solving …

Sensitivity and noise analysis of 4 km laser interferometric gravitational wave antennae
… from the ringdown of the quasi-normal modes of Kerr black holes. In addition, several possible future improvements to the detectors are outlined.

Frequency space analysis in General Relativity
… concerns the classical stability problem for black holes in the Kerr family which, conjecturally, exhausts the class of stationary asymmetric asymptotically flat vacuum black hole solutions. We study the Teukolsky master equation, a covariant wave-type PDE which, for different values of …

Stationary Anti-de Sitter Black Hole Solutions in and out of Equilibrium
… we numerically obtain a number of stationary black hole solutions to the Einstein-Maxwell equations with a negative cosmological constant. The AdS/CFT correspondence has caused an upsurge in studying anti-de Sitter (AdS) space, and under this duality, the study of classical black holes …

Spinning Black Hole Pairs: Dynamics and Gravitational Waves
Black hole binaries will be an important source of gravitational radiation for both ground-based and future space-based gravitational wave detectors. The study of such systems will offer a unique opportunity to test the dynamical predictions of general relativity when gravity is very strong. To …
