We have examined gravitational wave echo signals for nine binary black hole merger events observed by Advanced LIGO and Virgo during the first and second observation runs. To construct an echo template, we consider Kerr spacetime, where the event horizon is replaced by a reflective membrane. We use frequency-dependent reflection rate at the angular potential barrier, which is fitted to the numerical data obtained by solving Teukolsky equations. This reflection rate gives a frequency-dependent transmission rate that is suppressed at lower frequencies in the template. We also take into account the overall phase shift of the waveform as a parameter, which arises when the wave is reflected at the membrane and potential barrier. Using this template based on black hole perturbation, we find no significant echo signals in the binary black hole merger events.

  1. Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics

    gr-qc 2026-06 unverdicted novelty 6.0 of 10

    PhenomDECO analysis of GWTC-3 events finds all considered signals consistent with binary black holes once low-frequency noise effects are addressed via higher starting frequencies.

  2. Model-agnostic search of gravitational wave echoes in LVK data

    gr-qc 2025-12 conditional novelty 6.0 of 10

    A multi-detector phase-marginalized echo search finds no statistically significant long-lived quasinormal-mode echoes in GW150914, GW231226, and GW250114, and sets 90% upper limits on their network SNR and amplitude.

  3. Extreme mass-ratio inspirals and extra dimensions: Insights from modified Teukolsky framework

    gr-qc 2025-07 conditional novelty 5.0 of 10

    A modified Teukolsky equation and the Dudley-Finley approximation give nearly the same LISA detectability bound for the braneworld tidal charge, with MTE mismatches growing faster for high-eccentricity EMRIs.

  4. Towards a Non-singular Paradigm of Black Hole Physics

    gr-qc 2025-01 unverdicted novelty 1.0 of 10

    This is a review built around a week-long workshop, synthesizing the state and open problems of regular black holes and black hole mimickers as alternatives to singular black holes.
