The parameterized post-Einsteinian framework modifies inspiral waveform models to incorporate effects beyond General Relativity. We extend the existing model into the merger-ringdown regime. The modification introduced here adds a single degree of freedom that corresponds to a change in the binary coalescence time. Other merger properties remain as predicted by GR. We discuss parameter estimation with this model, and how it can be used to extract information from beyond-GR waveforms.

  1. 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.

  2. Modernising Reinforcement Learning-Based Navigation for Embodied Semantic Scene Graph Generation

    cs.AI 2026-03 unverdicted novelty 4.0 of 10

    Modern RL optimisation plus a finer-grained factorised discrete action space improves semantic scene-graph completeness and efficiency under a limited action budget.
