We study gravitational perturbations of slowly-rotating black holes in a general effective-field-theory extension of general relativity that includes up to eight-derivative terms. We show that two Schr\"odinger-like equations with spin-dependent effective potentials govern the odd - and even-parity master variables. These equations are coupled for parity-violating corrections, and this coupling affects the quasinormal modes even at linear order in the higher-derivative corrections, due to their isospectrality in general relativity. We provide results for the shifts in the fundamental quasinormal mode frequencies at linear order in the spin, which we expect to be valuable for high-precision phenomenology through future gravitational wave observations.

  1. Gravitational waveforms from binaries in higher-derivative gravity: a Love story

    gr-qc 2026-06 unverdicted novelty 7.0 of 10

    In higher-derivative gravity, the leading correction to extreme-mass-ratio inspiral waveforms and fluxes enters at 5PN order and is controlled by the ℓ=2 tidal Love number.

  2. Gravitational quasinormal modes of black holes in quadratic gravity

    gr-qc 2024-12 conditional novelty 7.0 of 10

    Axial gravitational quasinormal modes are computed for Schwarzschild and hairy black holes in Einstein-Weyl gravity, showing stability and new massive spin-2 tones.

  3. Extended parameterized spin expansion formalism for ringdown analysis with GW250114

    gr-qc 2026-06 unverdicted novelty 5.0 of 10

    Simultaneously sampling the EFT scaling index p̃ and length scale ℓ̃ in ParSpec shows p̃ is prior-dominated and the ℓ̃ ~ 83 km bound is mostly prior geometry.

  4. Gravitational radiations from periodic orbits around a black hole in the effective field theory extension of general relativity

    gr-qc 2025-12 unverdicted novelty 5.0 of 10

    Periodic orbits around EFTGR black holes produce gravitational waveforms whose substructures increase in complexity with higher zoom numbers.
