We present observational confirmation of Hawking's black-hole area theorem based on data from GW150914, finding agreement with the prediction with 97% (95%) probability when we model the ringdown including (excluding) overtones of the quadrupolar mode. We obtain this result from a new time-domain analysis of the pre- and postmerger data. We also confirm that the inspiral and ringdown portions of the signal are consistent with the same remnant mass and spin, in agreement with general relativity.

  1. A comprehensive look into the accuracy of SpEC binary black hole waveforms

    gr-qc 2025-10 conditional novelty 6.0 of 10

    Simulated black-hole merger waveforms accumulate numerical error over time, but the merger stage is not intrinsically less accurate once aligned on its own, and resolution-exchanged differences show no systematic bias...

    gr-qc 2026-06 conditional novelty 5.0 of 10

    Open-source numerical package for rational orbits and gravitational waves in static spherically symmetric spacetimes, validated on Schwarzschild and applied to an IMBH-Sgr A* EMRI.

  3. Hawking area law in quantum gravity

    gr-qc 2026-04 unverdicted novelty 5.0 of 10

    If Hawking's area law is taken as exact, nonlocal and Stelle quantum-gravity theories are forced to drop R^2 and (Riemann)^2 terms (or use singular Ricci-flat black holes), and the standard entropy-area law follows as...

    gr-qc 2025-10 conditional novelty 5.0 of 10

    A Bayesian, evidence-based analysis of 13 simulated black-hole ringdowns tabulates which quasinormal overtones, retrograde modes, and nonlinear (quadratic and cubic) modes are present at each start time, and finds no ...

  5. Potential science with GW250114 -- the loudest binary black hole merger detected to date

    gr-qc 2025-07 conditional novelty 5.0 of 10

    This simulation study forecasts that GW250114 can reveal measurable orbital eccentricity, decisive ringdown overtones, and tight black hole area theorem constraints.

  6. AthenaK simulations of the binary black hole merger GW150914

    gr-qc 2025-06 conditional novelty 5.0 of 10

    A new open-source GPU code, AthenaK, reproduces the GW150914 merger: remnant mass within 0.01%, spin within 0.02%, and waveform phase within about 0.35 radians of established simulations.

  7. Gravitational wave constraints on corrections to Bekenstein-Hawking Area Formula in classical F(R) gravity and quantum GR : implications for theory parameters

    gr-qc 2026-07 conditional novelty 2.0 of 10

    Assuming an extra 'absolute consistency' rule, gravitational-wave validation of the area theorem forces negative entropy corrections, which restricts F(R) gravity and would rule out two axions or an axion plus a graviton.
