Prediction
NANOGrav GW Background
A historic simplified comparison placed a matter-bounce slope near an external free-spectrum estimate under specific modeling choices. It cannot identify the origin of the signal or establish a bounce.
Current constraint
External PTA measurements remain relevant context, but this legacy simplified comparison does not exclude astrophysical alternatives or select a bounce scenario.
Key results
- Historic fitted values depend on the chosen simplified likelihood and model family
- This comparison does not exclude astrophysical alternatives
- Model choice and data representation materially affect inferred slopes
- Sampling diagnostics describe the historic computation, not physical confirmation
- PBH-induced gravitational-wave connections remain theoretical

Timeline
Historic model comparison retained as context; it is not a current program result or bounce detection.
Next steps
- openKeep this as a legacy consistency comparison rather than a bounce-detection claim
- openIf revisited, preregister a multi-model comparison with independent validation
