Black holes pile up at 10 solar masses, a hint of failed supernovae
Gravitational-wave data show merging black holes crowd near 10 solar masses and nearly vanish at 12–16. A model links the peak to stars that fail to explode.
What it does not show A gap is preferred but not required; under a second model the separation probability falls from 0.88 to 0.61, and no failed supernova was observed
