Evidence Mounts for Hierarchical Black Hole Mergers
A new catalog of 390 gravitational-wave events reveals evidence that some black holes are formed through previous mergers.
The brief
Researchers have documented 390 cosmic events involving black hole collisions. A recent ten-month observational period contributed 161 new detections to the record using LIGO facilities in the United States. Analysis of this data suggests that some black holes may have resulted from the merger of earlier black holes.
Coverage from MIT News, ScienceDaily, and the American Physical Society highlights the scale of this new catalog. Space Daily and Inshorts note the role of LIGO detectors in identifying these events and the specific existence of evidence supporting hierarchical mergers. Future developments will center on the classification of the hidden population of black holes identified in the research.
Coverage does not yet specify the timeline for further observations or additional data releases from the LIGO detectors.

Quick answers
How many black hole merger events are currently documented?
The current catalog contains 390 confirmed cosmic events.
What evidence suggests black holes have past lives?
Research indicates that some detected black holes are the result of hierarchical mergers, meaning they were formed from earlier black hole collisions.
Which instruments were used to detect these events?
The detections were made using LIGO detectors located in the United States.
