Listening for Darkness: Could Gravitational Waves Reveal Dark Matter's Signature
TL;DR Summary
A new study proposes that dense dark-matter clouds around spinning black holes could imprint a detectable signal on gravitational waves produced by merging black holes. Researchers analyzed 28 LIGO/Virgo/KAGRA events and found one—GW190728—whose waveform may carry such an imprint, though not a definitive detection. If true, this could provide a new way to probe dark matter using upcoming gravitational-wave observations and detector improvements, with the results published in Physical Review Letters.
