Theoretical and phenomenological aspects of gravitational wave physics

The recent direct detection of gravitational waves offer a whole new window to observe and study the universe. Predicted by general relativity, these ripples in the fabric of spacetime are generated by the most powerful astrophysical events of the cosmos. Investigating theoretical and phenomenological aspects of gravitational wave physics could provide the opportunity to improve the understanding of the fundamental physics that underlies the universe. Multiple detection methods will in the future allow gravitational waves to be observed across the wide spectrum of different wavelengths. In combination with electromagnetic observations, neutrino and cosmic-ray detection, in the context of multi-messenger astronomy, gravitational wave observations are key to understanding high-energy phenomena in the presence strong gravitational fields. The aim of this research is to provide a theoretical framework and data-analysis tools to determine constraints on or deviations from the standard model and general relativity to apply on future observations from next-generation detectors of gravitational waves.
