  1. Black-Hole Scattering in Einstein-scalar-Gauss-Bonnet: Numerical Relativity Meets Analytics

    gr-qc 2026-05 unverdicted novelty 8.0

    Numerical relativity simulations of black hole scattering in Einstein-scalar-Gauss-Bonnet gravity agree closely with effective-one-body analytic predictions.

  2. Gravitational Memory from Hairy Binary Black Hole Mergers

    gr-qc 2026-04 unverdicted novelty 8.0

    Gravitational memory from hairy binary black hole mergers in scalar-Gauss-Bonnet gravity differs from GR by a few percent due to altered nonlinear dynamics, with direct scalar contributions suppressed, and including m...

  3. Scalar memory from compact binary coalescences

    gr-qc 2026-05 conditional novelty 7.0

    In Ricci-coupled scalar-Gauss-Bonnet gravity, the change in scalar charge during binary black hole mergers generates a scalar memory contribution that modifies the total memory signal on observable timescales.

  4. Scalar memory from compact binary coalescences

    gr-qc 2026-05 conditional novelty 6.0

    Binary black hole mergers in Ricci-coupled scalar-Gauss-Bonnet gravity produce an observable scalar breathing memory signal from the merger-driven change in scalar charge, potentially matching the size of the theory's...

  5. Preheating and oscillon formation in Einstein-scalar-Gauss-Bonnet gravity

    gr-qc 2026-07 unverdicted novelty 5.0

    Simulations in Einstein-scalar-Gauss-Bonnet gravity show oscillons form with similar properties to standard cases but trigger EFT breakdown for large couplings via high local curvatures.

  6. Non-linear evolution of five-dimensional black strings in effective field theory

    hep-th 2026-06 unverdicted novelty 5.0

    Simulations of 5D black string instability in Einstein-Gauss-Bonnet gravity find that positive Gauss-Bonnet coupling caps curvature growth inside EFT validity, unlike negative coupling.

  7. 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

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