TItle: Gravitational waveform models for extreme mass ratio binaries via the self-force approach
Abstract: Extreme mass ratio binaries, where a stellar-mass compact object orbits a supermassive black hole, are key sources of gravitational waves for the future LISA mission. Detecting and characterising these sources requires template models that are rapid to generate and accurately track the phase evolution of the binary. In this talk I will overview how the perturbative "self-force" approach can be used to model these binaries. I will also highlight how recent results pushing the expansion to second-order in the mass ratio allows modelling of intermediate mass-ratio binaries with mass ratios as small as ~10:1.
