Primordial black holes (PBHs) are hypothetical objects formed due to gravitational collapse of density perturbations in the early phase of the universe (Hawking 1971; Carr & Hawking 1974).A PBH mass larger than ∼10 −18 M ⊙, where M ⊙ is the solar mass, is enough to prohibit evaporation via the Hawking radiation (Hawking … SpletSchools Click on the logo to access your school portal.

The radiation from accreting PBHs is capable of altering the evolution of the intergalactic medium (IGM), leaving marks on the global 21 cm signal in the dark ages.
Splet22. jun. 2024 · The detection of binary black hole coalescences by LIGO and Virgo has aroused the interest in primordial black holes (PBHs), because they could be both the progenitors of these black holes and a compelling candidate of dark matter (DM).
