| contents | <p>This manuscript presents statistically significant evidence for a coherent amplitude modulation at 0.090 Hz in the gravitational wave strain envelopes of events GW150914 and GW190521, based on public data from the LIGO–Virgo Open Science Center. A two-stage model comparison shows that the modulated waveform significantly outperforms a chirp-only baseline (p < 10⁻¹⁵). The anomaly is consistent across detectors and observing runs, with no known instrumental origin. This version has been submitted to <em>Physical Review Letters</em> on July 21, 2025, and is provided here as a public preprint under APS open-access policy.</p> |
