Research
Our research programme is organised around several interconnected projects spanning the full pipeline from analytical foundations to production-ready waveform models. Together, these projects deliver the gravitational self-force theory, computational infrastructure, and waveform templates needed for asymmetric-binary science across space- and ground-based gravitational-wave observatories.
Research Themes

Waveform Models
Building the production waveform models that next-generation gravitational-wave data-analysis pipelines will rely on.
Niels Warburton, Barry Wardell, Adam Pound
Second-order Source
Computing the source for the Einstein field equations at second order in the mass ratio — the foundation for post-adiabatic waveform accuracy.
Sam Upton, Barry Wardell, Adam Pound, Andrew Spiers
Hybrid Models
Connecting self-force results to effective-one-body and post-Newtonian frameworks.
Josh Mathews, David Trestini, Zach Nasipak, Barry Wardell, Adam Pound
