Waveforms and chirp

The signal measured by LIGO and Virgo from the neutron star merger GW170817 is compared  here to previously detected binary black hole mergers. All signals are shown starting at 30 Hertz, and the progression of GW170817 is shown in real time, accompanied by its conversion to audio heard at the end of the movie. GW170817 was observable for more than 30 times longer than any previous gravitational wave signal.
