Three Frequency Bands Could Catch Two Dozen of the Same Mergers
A forecast found the largest three-band yield when decihertz observations begin within about three years of the millihertz mission.
Summary
A forecast found the largest three-band yield when decihertz observations begin within about three years of the millihertz mission.
Using GWTC-4-derived populations and explicit mission timing, the study forecasts 23.5 plus 8.7 or minus 6.2 three-band events for one network at signal-to-noise eight. Subthreshold searches could raise yields four- to fivefold; these remain mission and population forecasts.
Why it matters
A forecast found the largest three-band yield when decihertz observations begin within about three years of the millihertz mission.
Limits and context
- Subthreshold searches could raise yields four- to fivefold; these remain mission and population forecasts.
Key claims
A forecast found the largest three-band yield when decihertz observations begin within about three years of the millihertz mission.
Qualification: Subthreshold searches could raise yields four- to fivefold; these remain mission and population forecasts.
