Our flagship output is a family of fast, accurate EMRI waveform templates suitable for LISA parameter estimation. The models are built around a two-stage offline–online architecture: expensive field-equation solves are performed once, ahead of time, while online evaluation produces year-long waveforms in milliseconds on a single GPU.
The resulting waveforms are accurate enough to enable real-time Bayesian inference and are distributed open-source through the Black Hole Perturbation Toolkit. Recent work has extended the framework from quasi-circular orbits in Schwarzschild to eccentric and inclined orbits in Kerr, with ongoing efforts to incorporate second-order self-force corrections.
Current focus
- Generic-orbit Kerr waveforms with second-order accuracy
- GPU optimisation of online waveform synthesis
- Validation against numerical relativity in the comparable-mass regime
- Integration into the LISA Distributed Data Processing Centre pipeline
