A meta-analysis of 1490 BBH merger rate predictions from 57 studies shows substantial subsets reproduce or underestimate the observed rate, indicating that apparent crises are model-dependent rather than universal.

Deconvolution of the GWTC-4.0 BBH merger rate reveals that long-delay tails in the delay time distribution are forbidden, constraining progenitor formation histories to decline more steeply than the star formation rate and disfavoring shallow power-law DTDs such as stable mass transfer.
Fitting 80 SNe Ic-BL lightcurves with a magnetar-plus-Ni model reveals a universal ejecta-mass–spin-period anti-correlation linking SNe Ic-BL, SLSNe, and FBOTs to a common magnetar origin.
A new main-sequence evolution framework implemented in COMPAS yields more massive helium cores, more compact stripped-star radii, and systematically higher black-hole masses than standard prescriptions.
No evidence for core-collapse formed low-spin IMBHs in GWTC-4, with 90% upper limit on merger rate of 0.077 Gpc^{-3} yr^{-1}, low-spin BH mass truncation at 65 solar masses consistent with pair-instability gap lower edge, and high-spin IMBHs from hierarchical mergers.
Simulations with a new tidal model in COMPAS predict that merging binary black holes from isolated evolution are strongly biased to low effective spins, with one third below 0.05 and only 3% above 0.5, but the high-spin fraction rises to 15% at higher redshifts.
Theoretical predictions for local BBH merger rates exceed observations by a factor >10 under conservative SFRD and metallicity assumptions, indicating need for revisions in stellar evolution.

Forbidden Formation Histories: The Binary Black Hole Merger Rate Disfavors Long Delay Times
Deconvolution of the GWTC-4.0 BBH merger rate reveals that long-delay tails in the delay time distribution are forbidden, constraining progenitor formation histories to decline more steeply than the star formation rate and disfavoring shallow power-law DTDs such as stable mass transfer.
