New model predicts how dark matter alters gravitational-wave signals from black hole mergers
By
Megan Arogeti
Summary
Physicists have developed a new model predicting how gravitational-wave emissions from binary black hole systems are altered when they move through dark matter. The model suggests that dark matter imprints a distinct signature on gravitational waves, which could potentially be detected by observatories like LIGO and Virgo. This provides a new indirect method for studying dark matter, which does not emit, absorb, or reflect light, by observing its gravitational effects on black hole mergers.
