The Science of Gravitational-Wave Sources and Beyond Compact Binary Coalescences
<p>"This work focuses on the field of gravitational-wave astronomy by extending the scope of detectable sources beyond compact binary coalescences, All the gravitational-wave detections so far come from compact binary coalescences. Focusing on core-collapse supernovae as promising sources for short …

Adaptive modal damping for advanced LIGO suspensions
Gravitational waves are predicted to exist by Einstein's Theory of General Relativity. The waves interact extremely weakly with the surrounding universe so only the most massive and violent events such as supernovae and collisions of black holes or neutron stars produce waves of sufficient …

Rotating perfect fluid bodies in Einstein's general theory of relativity
The study of rotating astrophysical bodies is of great importance in understanding the structure and development of the Universe. Rotating bodies, are not only of great interest in their own right, for example pulsars, but they have also been targeted as prime possible sources of gravitational …

From Measure Zero to Measure Hero: Periodic Kerr Orbits and Gravitational Wave Physics
A direct observational detection of gravitational waves - perhaps the most fundamental prediction of a theory of curved spacetime - looms close at hand. Stellar mass compact objects spiraling into supermassive black holes have received particular attention as sources of gravitational waves …

Source modelling at the dawn of gravitational-wave astronomy
The age of gravitational-wave astronomy has begun. Gravitational waves are propagating spacetime perturbations ($\textit{“ripples in the fabric of space-time”}$) predicted by Einstein’s theory of General Relativity. These signals propagate at the speed of light and are generated by powerful …

Gravitational Wave prediction from Galactic binary populations for LISA
… hole binaries, are expected to be the primary sources of gravitational waves (GWs) detectable by the Laser Interferometer Space Antenna (LISA). Detecting these sources provides an opportunity to unravel critical details about binary star evolution and the broader history of the Milky Way. Using …

Topics in the Detection of Gravitational Waves from Compact Binary Inspirals
… hole binaries - are among the most promising sources of gravitational waves observable by ground-based interferometric detectors. Despite numerous sophisticated engineering techniques, the gravitational wave signals will be buried deep within noise generated by various instrumental and …

Probes of strong-field gravity
… investigations focus on observables from the gravitational dynamics, i.e. when time derivatives are large: thus I focus on sources of gravitational waves. Extreme mass-ratio inspirals (EMRIs) can be very sensitive probes of strong-field physics. Predicting observables from EMRIs must be done …

ANALYZING AND IMPROVING INITIAL DATA FOR BINARY BLACK HOLES
Binary black holes are one of the most likely sources of gravitational radiation to be detected by projects such as LIGO and LISA. This radiation causes the binary to lose energy and angular momentum with the black holes adiabatically spiraling together. The strongest radiation is emitted at …

Novel aspects of the dynamics of binary black-hole mergers
The inspiral and merger of two black holes is among the most exciting and extreme events in our universe. Being one of the loudest sources of gravitational waves, they provide a unique dynamical probe of strong-field general relativity and a fertile ground for the observation of fundamental …

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 …
