Applications of Markov Chain Monte Carlo methods to continuous gravitational wave data analysis
A new algorithm for the analysis of gravitational wave data from rapidly rotating neutron stars has been developed. The work is based on the Markov Chain Monte Carlo algorithm and features enhancements specifically targeted to this problem. The algorithm is tested on both synthetic data and …

Bridging the gap between post-Newtonian theory and numerical relativity in gravitational-wave data analysis
… proven experimentally by a direct detection are gravitational waves. These are tiny distortions of the spacetime itself, and a world-wide effort to directly measure them for the first time with a network of large-scale laser interferometers is currently ongoing and expected to provide positive …

The detection and parameter estimation of binary black hole mergers
<p>In this dissertation we study gravitational-wave data analysis techniques for binary neutron star and black hole mergers. During its first observing run, the Advanced Laser Interferometer Gravitational-wave Observatory (Advanced LIGO) reported the</p> <p>first, direct observations of …

From Black Holes to the Big Bang: Astrophysics and Cosmology with Gravitational Waves and their Electromagnetic Counterparts
The growing catalog of gravitational-wave signals from compact object mergers has allowed us to study the properties of black holes and neutron stars more precisely than ever before and has opened a new window through which to probe the earliest moments in our universe’s history. Population-level …

Applications of deep learning for gravitational wave physics
… multidisciplinary field that demands fast data analysis. On the other hand, deep learning has greatly accelerated signal processing in many fields without sacrificing performance. This work shows that deep learning can be deployed for efficient binary neutron star merger predictions, …

Topics in gravitational-wave astronomy: Theoretical studies, source modelling and statistical methods
Astronomy with gravitational-wave observations is now a reality. Much of the theoretical research in this field falls under three broad themes: the mathematical description and physical understanding of gravitational radiation and its effects; the construction of accurate and computationally …

Data analysis of continuous gravitational waves
… our software, we have worked on simulated data as well as hardware injected signals of pulsars in the fourth LIGO science run (S4). While with the current sensitivity of our detectors we do not expect to detect any true Gravitational Wave signals in our data, we can still set upper limits …
