Cotesta et al. (2022) reanalyze the GW150914 ringdown, arguing against the presence of an overtone and suggesting claims of its detection in Isi et al. (2019) were driven by noise. Here we point out a number of technical errors in that analysis, including a software bug, and show that features highlighted as problematic are in fact expected and encountered in simulated data. After fixes, the code in used in Cotesta et al. (2022) produces results consistent with the presence of the overtone. All code and data are available at https://github.com/maxisi/gw150914_rd_comment

  1. Novel ringdown tests of general relativity with black hole greybody factors

    gr-qc 2026-04 unverdicted novelty 7.0

    GreyRing model based on greybody factors reproduces numerical relativity ringdown signals with mismatches of order 10^{-6} and enables a new post-merger consistency test of general relativity applied to GW250114.

  2. Accelerated Time-domain Analysis for Gravitational Wave Astronomy

    gr-qc 2026-03 unverdicted novelty 7.0

    Presents a practical fully time-domain end-to-end likelihood for gravitational-wave inference with structured linear algebra and GPU acceleration.

  3. Modeling the frequency-domain ringdown amplitude of comparable-mass mergers with greybody factors

    gr-qc 2025-12 unverdicted novelty 7.0

    A four-parameter greybody factor model reproduces the frequency-domain ringdown amplitude of comparable-mass aligned-spin mergers with mismatches of order 10^{-5}, improving existing models by two orders of magnitude.

  4. GW250114: testing Hawking's area law and the Kerr nature of black holes

    gr-qc 2025-09 accept novelty 5.0

    GW250114 data confirm the remnant black hole ringdown frequencies lie within 30% of Kerr predictions and that the final horizon area is larger than the sum of the progenitors' areas to high credibility.
