B. P. Abbott coauthored the collaborative analyses of GW150914. Fitting general relativity waveforms to LIGO data constrained the properties of the merging binary black hole.[ref]
Properties of the Binary Black Hole Merger GW150914 by B. P. Abbott and others. Author list and abstract: coherent analysis across the detector network using compact-binary waveform models and inferred source parameters.
A companion study converted detector control-loop signals into gravitational wave strain, with an optomechanical response model and independent checks of its measurement uncertainty.[ref]Calibration of the Advanced LIGO detectors for the discovery of the binary black-hole merger GW150914 by B. P. Abbott and others. Author list and abstract: time-domain calibration filters, optomechanical/feedback response and validation with radiation-pressure actuation.
