abstract

Gravitational-wave observations of binary black holes provide a suitable arena to test the fundamental nature of gravity in the strong-field regime. Using the data of the inspiral of 29 events detected by the LIGO-Virgo observatories, we perform a theory-agnostic test of the Kerr hypothesis. We compute the leading-order deviation to the gravitational waves emitted in the frequency domain and provide constraints on two deformation parameters ($\delta_1$ and $\delta_2$) belonging to a general class of axisymmetric non-Kerr black hole spacetimes proposed by Konoplya, Rezzolla & Zhidenko. Our study shows that all the analyzed events are consistent with the Kerr hypothesis. The LIGO-Virgo data provide stronger constraints on $\delta_1$ and $\delta_2$ than those obtained in our previous studies with X-ray data (Papers I and II), while, on the other hand, they cannot constrain the other deformation parameters of the Konoplya-Rezzolla-Zhidenko metric ($\delta_3$, $\delta_4$, $\delta_5$, and $\delta_6$).

  1. Time Evolution of Black Hole Perturbations in Quadratic Gravity

    gr-qc 2025-05 conditional novelty 6.0 of 10

    Gravitational perturbations of Einstein-Weyl black holes show late-time oscillatory tails decaying as t^{-5/6} and break the null-geodesic correspondence in the eikonal regime.

  2. Quasi-normal modes of slowly-rotating Johannsen black holes

    gr-qc 2024-12 conditional novelty 6.0 of 10

    For slowly rotating Johannsen black holes, the deformation parameter alpha_13 dominates the quasi-normal mode shifts, and ringdown data from GW170104 bound it to be consistent with zero.

  3. Observing the eye of the storm I: testing regular black holes with LVK and EHT observations

    gr-qc 2024-11 conditional novelty 5.0 of 10

    EHT shadow sizes and LIGO/Virgo/KAGRA inspiral waveforms allow only small values of the dimensionless regularity parameter ℓ in the Ghosh-Simpson-Visser regular black hole.

  4. Testing General Relativity with Black Holes

    gr-qc 2025-08 unverdicted novelty 1.0 of 10

    A status review of X-ray tests of the Kerr black hole hypothesis, concluding that current data are consistent with General Relativity, plus a speculative interstellar probe proposal.
