PBH dark matter spans all naturalness tiers, with some mechanisms as natural as WIMPs or freeze-in particles, determined by abundance map structure rather than candidate type.

abstract
Some indication of conditions that are necessary for the formation of black holes from the collision of bubbles during a supercooled phase transition in the the early universe are explored. Two colliding bubbles can never form a black hole. Three colliding bubbles can refocus the energy in their walls to the extent that it becomes infinite.

UNVERDICTED 3representative citing papers
The paper derives a quantitative relationship showing that the Kerr parameter a_* of PBHs from first-order phase transitions increases with latent heat α and decreases with transition rate β, reaching typical values of 10^{-3}.
Regular primordial black holes can evaporate completely like singular ones and yield the observed dark matter density under modified cosmological constraints.
