The catalog includes the strongest gravitational wave signal ever recorded, improves measurements of the universe's expansion rate, and provides new evidence for second-generation black holes formed through previous mergers. By analyzing hundreds of events instead of isolated discoveries, astronomers are gaining unprecedented insights into the evolution of the universe's most extreme objects.
