Primes¶
- Residual Analysis
- The residual-as-signal move ports from statistics to the physical sciences without modification — the Uranus-to-Neptune inference is the canonical case, and the same logic powers gravitational-wave template subtraction and cosmic-microwave-background foreground removal.
This sourceRecovers a gravitational-wave signal via matched-filter template subtraction, the residual-as-signal move in physics.
Supported in partVerified against the publisher's abstract
Backs only the gravitational-wave clause: the event was recovered by a matched-filter template search; silent on residuals, Uranus–Neptune and CMB foregrounds.
“The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203 000 years, equivalent to a significance greater than 5.1 σ .”

- Signal Detection Theory
- In astronomy and gravitational-wave detection, it is matched-filter threshold-setting against detector noise.
This sourceMatched-filter detection of a gravitational-wave signal against detector noise with explicit threshold and significance setting (matched-filter SNR 24, false-alarm rate < 1 per 203,000 yr).
- In astronomy and gravitational-wave detection, it is matched-filter threshold-setting against detector noise.
- Signal Extraction
- The signal model is an explicit template — the chirp \(h(t)\) predicted by general relativity for a given pair of inspiralling masses, sweeping up in frequency and amplitude as the bodies spiral together.
This sourceMatched-filtering a relativistic chirp template, weighted by the detector noise power spectral density, with residual and coincidence diagnostics.

The paper's abstract reports a signal sweeping upward in frequency that matches the general-relativistic waveform for inspiralling black holes, backing the template frame but not the explicit h(t) form or amplitude growth.
“The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10-21. It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole.”

Mechanisms¶
- Temporal Coincidence Detector
- And a burst of activity inflates the accidental rate everywhere at once, so during storms it can suppress real coincidences it would catch on a quiet night — the false-alarm-rate problem that any coincidence search must budget for.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 2 of 4 citations: 2 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
