The brief
Researchers have compiled a catalog of 390 gravitational wave detections, incorporating 161 new black hole collision events identified during a single ten-month run. These observations were made using LIGO detectors located in the US.
Coverage from ScienceDaily and Space Daily emphasizes that these detections reveal a hidden population of black holes. Specifically, Space Daily notes that two of the mergers may consist of black holes built from earlier black hole mergers.
Future attention focuses on the evidence for hierarchical black hole mergers, as highlighted by the American Physical Society.
