Project description
New models to refine black hole dynamics for future space missions
Next-generation gravitational wave detectors, including the LISA mission launching in 2035, will require highly precise models to analyse the complex data they collect. Gravitational wave astronomy has already transformed understanding of black holes, neutron stars and gravity, yet richer data demands more advanced waveform models. With the support of the Marie Skłodowska-Curie Actions programme, the TestGravity project will enhance black hole perturbation theory to create these accurate models, focusing on spinning black holes and alternative gravity theories. These models will help scientists better measure binary systems and test gravity laws. The proposed research will push the boundaries of gravitational wave science and fundamental physics.
Objective
Since 2015, gravitational waves have entered the realm of astronomy, providing a new channel to observe our universe. The groundbreaking measurements of gravitational waves have extended our knowledge of gravity, black holes, and neutron stars. Like all measurements probing new, extreme regimes, gravitational wave astronomy has the potential to uncover new fundamental physics.
Analysing gravitational wave signals requires accurate theoretical waveform models. Black hole perturbation theory (BHPT) has significantly contributed to waveform modelling and helped us understand the nature of black hole dynamics. The next generation of gravitational wave detectors will produce richer data requiring more precise models. The Laser Interferometer Space Antenna (LISA) mission was recently adopted by the European Space Agency and is planned to launch in 2035. Producing precise measurements of binaries and testing gravity are two key science goals for the LISA mission, but such measurements will require precision waveform models beyond our current capabilities.
This proposal will advance waveform modelling to the required accuracy for future detectors by extending BHPT. I will extend BHPT models in General Relativity to second perturbative order for spinning black hole spacetimes—and create new models in alternative theories of gravity. The waveforms produced will help measure binaries and perform tests of gravity with LISA and ground-based detectors.
UCD is the ideal sponsor for my fellowship because of its world-leading research group in BHPT. Combining my expertise in the theory of BHPT and alternative theories of gravity with UCD's expertise in practical BHPT waveform calculation will cultivate knowledge exchange and a successful project impact. An MSCA fellowship will result in my research testing our theory of gravity with gravitational wave astronomy.
