abstract

Quasinormal modes of rapidly rotating black holes were recently computed in a generic effective-field-theory extension of general relativity with higher-derivative corrections. We exploit this breakthrough to perform the most complete search for signatures of new physics in black hole spectra to date. We construct a template that describes the post-merger gravitational-wave emission in comparable-mass binary black hole mergers at current detector sensitivity, notably including isospectrality breaking. The analysis of all events with detectable quasinormal-driven ringdown signatures yields no evidence of higher-derivative corrections in the spectra, and we set an upper bound $\ell \lesssim$ 35 km on the length scale of new physics. Looking ahead, our scheme enables new studies on the capabilities of future detectors to robustly search for signatures of new gravitational physics.

  1. Functional inference on deviations from General Relativity

    gr-qc 2025-07 conditional novelty 6.0 of 10

    GRANITA reconstructs functional, parameter-dependent deviations from General Relativity in gravitational-wave data using Gaussian process regression with free node values.

  2. Extreme mass-ratio inspiral within an ultralight scalar cloud I. Scalar radiation

    gr-qc 2025-07 conditional novelty 6.0 of 10

    Scalar radiation from an EMRI in an ultralight scalar cloud is computed semi-analytically, showing dipole clouds decelerate and quadrupole clouds accelerate the inspiral, with up to about 100 rad dephasing after 18 months.

  3. Discrete symmetries of modified Teukolsky equations

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Complex modifications of the Teukolsky potential break m=0 QNM degeneracy and can inject non-physical mode branches when frequency-domain multipole-dependent potentials are evolved in time.

  4. 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.

  5. 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.

  6. Revisiting GW150914 with a non-planar, eccentric waveform model

    gr-qc 2025-05 conditional novelty 5.0 of 10

    Using a waveform model that includes both eccentricity and spin precession, the authors confirm GW150914 was a quasi-circular, slowly spinning black hole merger, with eccentricity below 0.08 at 15 Hz.
