The upper edge of the PISN black hole mass gap shifts by up to 30 solar masses due to nuclear reaction rate uncertainties, primarily the 12C(α,γ)16O rate, while remaining robust to resolution variations unlike the lower edge.

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.
