New Black-Hole-Merger Detections Hint at Exotic Astrophysical Scenarios
An exciting new era in astronomy began billions of years ago with a collision between two black holes that sent gravitational waves rippling through the universe. In 2019, signals from these waves were detected at the gravitational wave observatory LIGO and the detector Virgo. Fast forward to 2022, Princeton researchers announced the discovery of 10 new black hole mergers hiding in the data from LIGO and Virgo gravitational wave detectors.
