We study two large classes of alternative theories, modifying the action through algebraic, quadratic curvature invariants coupled to scalar fields. We find one class that admits solutions that solve the vacuum Einstein equations and another that does not. In the latter, we find a deformation to the Schwarzschild metric that solves the modified field equations in the small coupling approximation. We calculate the event horizon shift, the innermost stable circular orbit shift, and corrections to gravitational waves, mapping them to the parametrized post-Einsteinian framework.

  1. Static Black Holes and Iyer-Wald Entropy in $f(\mathcal{R},\mathcal{K})$ Gravity

    gr-qc 2026-07 accept novelty 6.0 of 10

    In f(R,K) gravity with f=-X^{1-n}, first-order Schwarzschild corrections yield Iyer–Wald entropy S = S_BH + λ Υ_n S_BH^{n+1}.

  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. Supermassive black hole scalarization and effective field theory

    gr-qc 2025-06 accept novelty 6.0 of 10

    A canonical two-scalar EFT cannot naturally produce supermassive-only black hole scalarization, because the generated G^2 term has the wrong sign and is suppressed.

  4. Chaotic imprints of dark matter in extreme mass-ratio inspirals

    gr-qc 2026-02 reject novelty 4.0 of 10

    A toy model shows that adding a hand-made angle-dependent force to dark-matter spacetimes produces visual chaos and irregular numerical-Kludge waveforms, but the force is not a realistic dark-matter perturbation.

  5. 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.
