The gravitational-wave signal GW230814. The top panel shows the time-frequency representation of the signal where brighter regions indicate larger amplitude. The CWT acronym points to the method used to construct this time-frequency representation, based on the Continuous Wavelet Transform. The bottom panel shows the signal represented as a time series. The blue and purple lines show two different methods of reconstruction for the signal waveform. It is clear that the signal is a compact binary coalescence and the data are in good agreement with the reconstructions until the ringdown part. Being such a loud signal allows us to make this wonderfully precise reconstruction!
