  "abstract": "The hot big bang may have emerged from evaporation of primordial black holes (PBHs) lighter than 10 9 g . Standard monochromatic treatments predict nearly simultaneous evaporation, abrupt reheating, and a large poltergeist scalar-induced gravitational wave signal. We confront this expectation with the irreducible collapse mass tail predicted by general relativity, d f PBH / d ln M ∝ M 3.78 , which smooths reheating, suppresses the signal by orders of magnitude, and reopens the ultralight PBH window.",
