Accurate modeling of resonances in Kerr EMRIs

Investigate accurate modeling of resonances in Kerr black-hole extreme-mass-ratio inspirals for gravitational-wave modeling and data analysis.

Background

The paper notes that resonances in integrable Kerr black-hole extreme-mass-ratio inspirals already constitute an unresolved issue for EMRI modeling and gravitational-wave data analysis. The tidal perturbations considered in the paper break integrability and introduce additional resonant structures, making the accurate treatment of resonances in waveform modeling even more challenging.

References

Since, resonances in Kerr BHs, where integrability holds, are already an open issue in the EMRI modeling and data analysis , one can assume that breaking integrability should lead to stronger effects in the resulting waveforms of non-integrable EMRIs, thus making the issue of modeling resonances accurately even more complicated .
