Primordial black holes (PBHs) are a profound signature of primordial cosmological structures and provide a theoretical tool to study nontrivial physics of the early Universe. The mechanisms of PBH formation are discussed and observational constraints on the PBH spectrum, or effects of PBH evaporation, are shown to restrict a wide range of particle physics models, predicting an enhancement of the ultraviolet part of the spectrum of density perturbations, early dust-like stages, first order phase…

Spins of primordial black holes formed in different cosmological scenarios
Primordial black holes (PBH) could account for all or part of dark matter, as well as for some LIGO events. We discuss the spins of primordial black holes produced in different cosmological…
Primordial Black Holes from Warm Inflation
Primordial Black Holes (PBHs) serve as a unique probe to the physics of the early Universe phenomenon, cosmic inflation. In light of this, we study the formation of PBHs by the collapse of overdense…
Primordial black hole evolution in two-fluid cosmology
Several processes in the early universe might lead to the formation of primordial black holes with different masses. These black holes would interact with the cosmic plasma through accretion and…
On Mass Spectra of Primordial Black Holes
Evidence for the primordial black holes (PBH) presence in the early Universe renews permanently. New limits on their mass spectrum challenge existing models of PBH formation. One of the known models…
Primordial seeds of supermassive black holes
Cosmological constraints on primordial black holes
Primordial Black Holes(PBH) may have formed from collapse of high-density primordial fluctuations in the early Universe. Interest for PBH has been stirred anew by the LIGO detection of gravitational…
Signatures of primordial black hole dark matter
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 breaking. In the early…
Primordial black holes from pre-big bang inflation
We discuss the possibility of producing a significant fraction of dark matter in the form of primordial black holes in the context of the pre-big bang inflationary scenario. We take into account, to…
Interstellar gas heating by primordial black holes
Interstellar gas heating is a powerful cosmology-independent observable for exploring the parameter space of primordial black holes (PBHs) formed in the early Universe that could constitute part of…
Primordial black hole dark matter in dilaton-extended two-field Starobinsky inflation
We investigate the production of primordial black holes and their contribution to the presently observed dark matter in a dilaton two-field extension of Starobinsky's quadratic $f(R)$ model of…

CLASSICALITY OF PRIMORDIAL FLUCTUATIONS AND PRIMORDIAL BLACK HOLES
The production of Primordial Black Holes (PBH) from inflationary perturbations provides a physical process where the effective classicality of the fluctuations does not hold for certain scales. For…

Formation of intermediate-mass black holes as primordial black holes in the inflationary cosmology with running spectral index
Formation of primordial black holes (PBHs) on astrophysical mass scales is a natural consequence of inflationary cosmology if the primordial perturbation spectrum has a large and negative running of…
Primordial black holes in braneworld cosmologies: Astrophysical constraints

Blue spectra and induced formation of primordial black holes
We investigate the statistical properties of primordial black hole (PBH) formation in the very early Universe. We show that the high level of inhomogeneity of the early Universe leads to the…
Peculiar relics from Primordial Black Holes in the inflationary paradigm
Depending on various assumptions on the energy scale of inflation and assuming a primordial power spectrum of a step‐like structure, we explore new possibilities for Primordial Black Holes (PBH) and…
