The Laser Interferometric Space Antenna (LISA) will observe supermassive black hole binary mergers with amplitude signal-to-noise ratio of several thousands. We investigate the extent to which such observations afford high-precision tests of Einstein's gravity. We show that LISA provides a unique opportunity to probe the non-linear structure of post-Newtonian theory both in the context of general relativity and its alternatives.

  1. Tests of general relativity at the fourth post-Newtonian order with GW230627 and GW250114

    gr-qc 2026-06 unverdicted novelty 7.0 of 10

    Bayesian analysis of GW230627 and GW250114 finds no deviation from GR at 4PN and 4.5PN orders, setting the first empirical baseline with 90% intervals of order O(1)-O(10).

  2. Impact of numerical-relativity waveform calibration on parametrized post-Einsteinian tests

    gr-qc 2026-03 accept novelty 6.0 of 10

    NR late-inspiral calibration systematics in IMRPhenomD produce false ppE GR violations at O5 SNRs ≳60; an uncertainty-aware baseline restores consistency with GR up to SNR 330.

  3. 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.

  4. A $\chi^2$ statistic for the identification of strongly lensed gravitational waves from compact binary coalescences

    gr-qc 2025-02 conditional novelty 6.0 of 10

    A chi-squared test built from gravitational wave search templates can separate lensed event pairs from unlensed pairs with accuracy comparable to slower Bayesian methods.

  5. Tests of General Relativity with the Binary Black Hole Signals from the LIGO-Virgo Catalog GWTC-1

    gr-qc 2019-03 accept novelty 6.0 of 10

    Binary black hole signals in GWTC-1 are consistent with general relativity predictions, with an improved graviton mass bound of mg ≤ 4.7 × 10^{-23} eV/c² at 90% credible level.

  6. Biases in Tests of General Relativity from Microlensed Gravitational-Wave Signals

    gr-qc 2026-07 conditional novelty 5.0 of 10

    Microlensing in the wave-optics regime can push standard LIGO-Virgo-KAGRA general-relativity tests to false ~4–4.5σ deviations, even for signals that are perfectly consistent with GR.

  7. Inspiral tests of general relativity and waveform geometry

    gr-qc 2026-02 conditional novelty 5.0 of 10

    The power of ppE-style GR tests comes from waveform geometry: GR parameter biases absorb most of any smooth phase deviation, and SVD finds the few orthogonal directions that remain.

  8. Neural Post-Einsteinian Test of General Relativity with the Third Gravitational-Wave Transient Catalog

    gr-qc 2025-10 unverdicted novelty 5.0 of 10

    Neural post-Einsteinian analysis of GWTC-3 finds no GR violation and sets constraints covering both post-Newtonian and beyond-post-Newtonian deviations in a single theory-agnostic setup.

  9. Tests of General Relativity with GW230529: a neutron star merging with a lower mass-gap compact object

    gr-qc 2024-06 conditional novelty 5.0 of 10

    Parameterized inspiral tests on GW230529 find consistency with GR, with |δφ̂_{-2}| ≲ 8×10^{-5} and ℓ_GB ≲ 0.51 M_⊙ in ESGB theories.

  10. Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog

    gr-qc 2020-10 accept novelty 5.0 of 10

    No evidence for deviations from general relativity is found in LIGO-Virgo binary black hole events, with improved constraints on waveform parameters, graviton mass, and ringdown properties.

  11. Probing missing physics from inspiralling compact binaries via time-frequency tracks

    gr-qc 2025-07 conditional novelty 4.0 of 10

    A new time-frequency consistency test, built by stacking pixel energies along scaled orbital frequency tracks, flags deviations from General Relativity in injections and in GW190814 when higher modes are omitted.

  12. The Science of the Einstein Telescope

    gr-qc 2025-03 unverdicted novelty 3.0 of 10

    The paper provides state-of-the-art predictions for the Einstein Telescope's impact on fundamental physics, cosmology, compact-object astrophysics, and multi-messenger astronomy across its proposed configurations.
