Primordial Black Holes as Dark Matter: Recent Developments

Bernard Carr, Florian Kuhnel

Primordial black holes remain viable as dark matter in three mass windows and could seed cosmic structures.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

PBHs might have important consequences and resolve various cosmological conundra even if they have only a small fraction of the dark-matter density. In particular, those larger than 10^3 M_⊙ could generate cosmological structures through the seed or Poisson effect.

C2weakest assumption

The completeness and accuracy of the existing observational constraints that define the allowed mass windows; if any constraint is overstated or incomplete, the viable windows could close or reopen.

C3one line summary

Primordial black holes in specific mass ranges could account for some or all dark matter while resolving structure-formation and seed problems in standard cosmology.
