abstract

In a recent paper (arXiv:1612.00266), we reported the results of the first search for echoes from Planck-scale modifications of general relativity near black hole event horizons using the public data release by the Advanced LIGO gravitational wave observatory. While we found tentative evidence (at $\simeq 3 \sigma$ level) for the presence of these echoes, our statistical methodology was challenged by Ashton, et al. (arXiv:1612.05625), just in time for the holidays! In this short note, we briefly address these criticisms, arguing that they either do not affect our conclusion or change its significance by $\lesssim 0.3\sigma$. The real test will be whether our finding can be reproduced by independent groups using independent methodologies (and ultimately more data).

  1. 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.

  2. Spectral Lines of Quantized, Spinning Black Holes and their Astrophysical Relevance

    gr-qc 2019-09 conditional novelty 6.0 of 10

    Including black hole spin increases the natural widths of quantized-area states, making spectral lines overlap for the most common area-quantization models.
