The Binary Black Hole Grand Challenge Alliance (BBH Challenge Alliance) was a scientific collaboration of international physics institutes and research groups dedicated to simulating the sources and predicting the waveforms for gravitational waves, in anticipation of gravitational radiation experiments such as LIGO.^{[1] [2]}

History

The BBH Challenge Alliance was established in 1993.^[3] This was an alliance of numerical relativity groups engaged in a friendly competition to tackle the grand challenge of simulating binary black hole collisions for the purpose of understanding gravitational wave signatures that would be detected by experiments such as LIGO.^[4]
