Exploring the Relativistic Transient Universe with Gravitational Waves (gravity)
The long-anticipated birth of gravitational-wave astronomy will occur in the next few years with the advent of the Advanced LIGO and Advanced Virgo gravitational-wave detectors. These instruments will open a new channel for studying the most extreme phenomena and environments found in nature, including gamma-ray bursts, core-collapse supernovae, and black-hole mergers. The inner engines of these systems are either obscured or inherently invisible to electromagnetic observations. Furthermore, the associated gravitational-wave emission typically depends on poorly understood physics, such as the equation-of-state of matter at supra-nuclear densities. Gravitational waves will therefore provide an exciting new probe of these astrophysical systems, for example constraining the neutron star equation-of-state, and providing laboratories for tests of fundamental physics and cosmology. However,
realising the potential of gravitational waves poses a significant challenge: state-of-the-art techniques for detecting and interpreting gravitational waves require precise theoretical models of the gravitational-wave emission, and hence are not applicable to most gravitational-wave sources. This project aims at maximising the scientific exploitation of gravitational waves through advancements beyond current state-of-the-art in rapid automated analyses, advanced signal/background discrimination, and waveform reconstruction. The goals of this project are:
(i) to develop the model independent techniques needed to robustly detect gravitational waves from relativistic transient events, and determine the signal structure;
(ii) to apply these to data from the Advanced LIGO / Advanced Virgo network to detect GWs; and
(iii) to use detected GWs as probes of relativistic systems and fundamental physics.
This project is available to students applying for funded PhD studentships and may be altered or amended.
Studentships will be awarded to successful applicants from all applications received.
