Although the dark matter is usually assumed to be made up of some form of elementary
particle, primordial black holes (PBHs) could also provide some of it. However, various …

We review the formation and evaporation of primordial black holes (PBHs) and their
possible contribution to dark matter. Various constraints suggest they could only provide …

Seven observations point towards the existence of primordial black holes (PBH), constituting
the whole or an important fraction of the dark matter in the Universe: the mass and spin of …

Primordial black holes (PBHs) represent a natural candidate for one of the components of
the dark matter (DM) in the Universe. In this review, we shall discuss the basics of their …

Primordial black holes (PBHs) could provide the dark matter in various mass windows below
102 M⊙ and those of 30 M⊙ might explain the LIGO events. PBHs much larger than this …

The nonbaryonic dark matter of the Universe is assumed to consist of new stable forms of
matter. Their stability reflects symmetry of micro-world and mechanisms of its symmetry …

The possibility that the dark matter comprises primordial black holes (PBHs) is considered,
with particular emphasis on the currently allowed mass windows at 1 0 16–1 0 17 g, 1 0 20 …

We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …

The detection of gravitational waves from mergers of tens of Solar mass black hole binaries
has led to a surge in interest in primordial black holes (PBHs) as a dark matter candidate …

We set a new upper limit on the abundance of primordial black holes (PBH) based on
existing X-ray data. PBH interactions with interstellar medium should result in significant …
