We consider the possibility that massive primordial black holes are the dominant form of dark matter. Black hole formation generates entropy fluctuations that adds a Poisson noise to the matter power spectrum. We use Lyman-alpha forest observations to constrain this Poisson term in matter power spectrum, then we constrain the mass of black holes to be less than few times 10^4 solar mass. We also find that structures with less than ~ 10^3 primordial black holes evaporate by now.

Lower bound on the primordial black hole merger rate
Even if nearly all early PBH binaries are disrupted, the re-formed and perturbed binaries merge often enough to rule out PBHs as all of the dark matter in the 1 to 100 solar mass range.

In mixed ULDM-PBH halos the continuum PBH contribution alters soliton structure at the tens-of-percent level while discrete shot noise induces mode transitions too slow to matter on galactic timescales.
