LIGO Observes a Third Gravitational Wave Signal
As was the case with the first two detections, the waves were generated when a pair of black holes merged to form a larger black hole. The signal was first seen at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Hannover. Scientists at the AEI in Potsdam and Hannover and at the Leibniz Universität Hannover have made crucial contributions in several key areas: highly accurate waveform models to detect the signal and infer astrophysical information from it, efficient data analysis methods running on powerful computer clusters, and advanced detector technology. The detection leads to an improved estimate for the rate of black hole mergers and is fully consistent with Einstein’s theory of general relativity.
