In this review article I attempt to summarise past and present-ongoing-work on the problem of the inspiral of a small body in the gravitational field of a much more massive Kerr black hole. Such extreme mass ratio systems, expected to occur in galactic nuclei, will constitute prime sources of gravitational radiation for the future LISA gravitational radiation detector. The article's main goal is to provide a survey of basic celestial mechanics in Kerr spacetime and calculations of gravitational waveforms and backreaction on the small body's orbital motion, based on the traditional `flux-balance' method and the Teukolsky black hole perturbation formalism.

  1. Constraining polymerized black holes with quasi-circular extreme mass-ratio inspirals

    gr-qc 2024-12 conditional novelty 6.0 of 10

    A future LISA observation of an extreme-mass-ratio inspiral around a polymerized black hole could constrain the quantum parameter k-hat to about 0.003, roughly two orders of magnitude tighter than current black hole s...

  2. Periodic orbits and their gravitational waves in EMRIs: supermassive black hole affected by galactic dark matter halos

    gr-qc 2025-10 conditional novelty 5.0 of 10

    Periodic zoom-whirl orbits and their gravitational waveforms in NFW, Beta, and Moore dark matter halos deviate from Schwarzschild predictions by an amount set by halo mass and radius, with NFW and Beta nearly identica...

  3. Distinguishing scale-dependent Planck stars from renormalization group improved Schwarzschild black holes by Gravitational waves

    gr-qc 2025-06 conditional novelty 4.0 of 10

    Gravitational-wave strains from analytic-kludge EMRI models can distinguish scale-dependent Planck stars from renormalization-group improved Schwarzschild black holes, at least for the chosen orbit parameters.

  4. Periodic orbits and their gravitational wave radiations in black hole with dark matter halo

    gr-qc 2025-02 conditional novelty 4.0 of 10

    A Hernquist-like dark matter halo changes the energies, angular momenta, and gravitational waveforms of periodic orbits around a supermassive black hole, compared with vacuum Schwarzschild.
