abstract

An effective field theory framework, the Standard-Model Extension, is used to investigate the existence of Lorentz and CPT-violating effects during gravitational wave propagation. We implement a modified equation for the dispersion of gravitational waves, that includes isotropic, anisotropic and birefringent dispersion. Using the LIGO-Virgo-KAGRA algorithm library suite, we perform a joint Bayesian inference of the source parameters and coefficients for spacetime symmetry breaking. From a sample of 45 high confidence events selected in the GWTC-3 catalog, we obtain a maximal bound of $3.19 \times 10^{-15}$~m at 90\% CI for the isotropic coefficient $k_{(V)00}^{(5)}$ when assuming the anisotropic coefficients to be zero. The combined measurement of all the dispersion parameters yields limits on the order of $10^{-13}$~m for the 16 $k_{(V)ij}^{(5)}$ coefficients. We study the robustness of our inference by comparing the constraints obtained with different waveform models, and find that a lack of physics in the simulated waveform may appear as spacetime symmetry breaking-induced dispersion for a subset of events.

  1. Gravitational-wave generation in the presence of Lorentz invariance violation

    gr-qc 2025-06 conditional novelty 7.0 of 10

    Gravitational waves in a class of Lorentz-violating gravity theories would have amplitude components that do not decay with distance, strongly constraining those theories.

  2. Constraints on parity and Lorentz violations from gravitational waves: a comparison between single-parameter and multi-parameter analysis

    gr-qc 2025-07 conditional novelty 5.0 of 10

    Multi-parameter and single-parameter gravitational-wave analyses yield comparable parity and Lorentz violation constraints for three models, but degeneracies weaken the multi-parameter result when two parameters modif...

  3. Constraining Lorentz and parity violations in gravity with multiband gravitational wave observations

    gr-qc 2026-01 conditional novelty 4.0 of 10

    Future multiband GW networks could tighten Lorentz- and parity-violation energy-scale bounds by up to several orders of magnitude, with massive binaries best for low-frequency and loud binaries for high-frequency effects.

  4. Constraining parity and Lorentz violations in gravity with future ground- and space-based gravitational wave detectors

    gr-qc 2025-02 conditional novelty 4.0 of 10

    Future gravitational wave detectors could tighten constraints on parity- and Lorentz-violating energy scales by one to three orders of magnitude, with space-based detectors winning for certain frequency dependencies.
