Comparison of gravitational-wave signal templates from recent LIGO observations

This figure shows reconstructions of the three confident and one candidate (LVT151012) gravitational wave signals detected by LIGO to date, including the most recent detection GW170104. Each row shows the signal arriving at the Hanford detector as a function of time. The thickness of the curves indicates the 90% confidence interval on the model parameters. Only the portion of each signal that LIGO was sensitive to is shown here (the final seconds leading up to the black hole merger). LIGO/Caltech/MIT/University of Chicago (Ben Farr)
