Overview
Advanced view of Waveforms, Standard Sirens & Future Detectors
A gravitational-wave waveform is a time series whose phase, frequency, amplitude, and polarization encode the dynamics of its source. Compact-binary signals can also act as standard sirens because general relativity predicts an intrinsic amplitude scale that allows luminosity distance to be inferred directly from the wave signal.
Standard sirens offer an independent route to the Hubble constant, future detectors will probe early black-hole populations and precision strong-field gravity, and multi-band observations can follow some systems across years of inspiral.
