Mechanism
Mechanism of Waveforms, Standard Sirens & Future Detectors
The amplitude observed at Earth decreases with luminosity distance, while the waveform's phase evolution reveals intrinsic source scales. Degeneracies—especially between distance and inclination—are reduced by multiple detectors or electromagnetic information. Space interferometers can observe lower-frequency systems long before they enter ground-based bands.
