We update the constraints on the fraction of the Universe that may have gone into primordial black holes (PBHs) over the mass range 10−5 to 1050 g. Those smaller than ∼1015 g would have evaporated by now due to Hawking radiation, so their abundance at formation is constrained by the effects of evaporated particles on big bang nucleosynthesis, the cosmic microwave background (CMB), the Galactic and extragalactic γ-ray and cosmic ray backgrounds and the possible generation of stable Planck mass… 
Gravitational waves from a universe filled with primordial black holes
Ultra-light primordial black holes, with masses m PBH < 109g, evaporate before big-bang nucleosynthesis and can therefore not be directly constrained. They can however be so abundant that they
Stellar mass primordial black holes as cold dark matter
Primordial black holes (PBHs) might have formed in the early Universe due to the collapse of density fluctuations. PBHs may act as the sources for some of the gravitational waves recently observed.
Testing Primordial Black Holes with multi-band observations of the stochastic gravitational wave background
The mass distribution of Primordial Black Holes (PBHs) is affected by drops in the pressure of the early Universe plasma. For example, events in the standard model of particle physics, such as the W

The LIGO/Virgo collaboration have by now detected the mergers of ten black hole binaries via the emission of gravitational radiation. The hypothesis that these black holes have formed during the
Solar mass primordial black holes in moduli dominated universe
We explore the prospect of producing primordial black holes around the solar mass region during an early matter domination epoch. The early matter-dominated epoch can arise when a moduli field comes
Baryogenesis from ultralight primordial black holes and strong gravitational waves from cosmic strings
Ultralight primordial black holes (PBHs)(≲109g) completely evaporate via Hawking radiation (HR) and produce all the particles in a given theory regardless of their other interactions. If the right
Press–Schechter primordial black hole mass functions and their observational constraints
We present a modification of the Press–Schechter (PS) formalism to derive general mass functions for primordial black holes (PBHs), considering their formation as being associated with the
Axion-like particles from primordial black holes shining through the Universe
We consider a cosmological scenario in which the very early Universe experienced a transient epoch of matter domination due to the formation of a large population of primordial black holes (PBHs)
Constraints on a mixed model of dark matter particles and primordial black holes from the galactic 511 keV line
The galactic 511 keV gamma-ray line has been observed since 1970's, and was identified as the result of electron-positron annihilation, but the origin of such positrons is still not clear. Apart from
