The Combined Allowed Fraction of Primordial Black Hole Dark Matter by Mass Window
Year: 2026
Type: article
Abstract: No single observation settles whether primordial black holes are the dark matter. The answer lives in the accumulation: evaporation products bound the light end, spectral distortions and femtolensing patrol the middle distances, microlensing and capture and merger rates divide the heavy ranges among them, and each bound was derived with its own assumptions, environments, and conventions. The headline computed values are: min f overall = 1e-08; windows tested = 11; binding at solar = merger. This is a simulated and computed study, not a measurement; the code and outputs are deposited alongside the text.
