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 cosmic QCD epoch and make up all of the cosmic dark matter, has been rejected by many authors reasoning that, among other constraints, primordial black hole (PBH) dark matter would lead to orders of magnitude larger merger rates than observed. We revisit the calculation of the present PBH merger rate…

Eliminating the LIGO bounds on primordial black hole dark matter
Primordial black holes (PBHs) in the mass range (30–100) M⊙ are interesting candidates for dark matter but are tightly constrained by the LIGO merger rate. In deriving these constraints, PBHs were
The importance of priors on LIGO-Virgo parameter estimation: the case of primordial black holes
The black holes detected by current and future interferometers can have diverse origins. Their expected mass and spin distributions depend on the specifics of the formation mechanisms. When a

[Abridged] The primordial scalar power spectrum is well constrained on large scales, primarily by the observations of the anisotropies in the cosmic microwave background (CMB). Over the last few
Effect of clustering on primordial black hole microlensing constraints
Stellar microlensing observations tightly constrain compact object dark matter in the mass range (10 − 11 − 10 3 ) M (cid:12) . Primordial Black Holes (PBHs) form clusters, and it has been argued
Enhanced power on small scales and evolution of quantum state of perturbations in single and two field inflationary models
With the detection of gravitational waves from merging binary black holes, over the last few years, there has been a considerable interest in the literature to understand if these black holes could
Constraints on PBH as dark matter from observations: a review
: Primordial black holes (PBHs) are a fascinating candidate for being the dark matter, albeit one which has been heavily constrained. This review presents an in depth look at those observational
Survival of black holes through a cosmological bounce
We analyze whether a black hole can exist and survive in a universe that goes through a cosmological bounce. To this end, we investigate a central inhomogeneity embedded in a bouncing cosmological
Capture of primordial black holes in extrasolar systems
. The vast datasets associated with extrasolar systems promise to offer sensitive probes of new physics in the near future. We consider the possibility that such systems may capture primordial black
Dancing in the dark: detecting a population of distant primordial black holes
. Primordial black holes (PBHs) are compact objects proposed to have formed in the early Universe from the collapse of small-scale over-densities. Their existence may be detected from the observation
The Hunt for Light Primordial Black Hole Dark Matter with Ultra-High-Frequency Gravitational Waves
: Light primordial black holes may comprise a dominant fraction of the dark matter in our Universe. This paper critically assesses whether planned and future gravitational wave detectors in the

Consistency of Primordial Black Hole Dark Matter with LIGO/Virgo Merger Rates.
This paper computes current merger rates in PBH clusters in which the typical PBH resides and suggests that in both scenarios PBH merger rates made with a minimum of assumptions match most LIGO/Virgo observed rates very well.
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.
Primordial black holes confront LIGO/Virgo data: current situation
The LIGO and Virgo Interferometers have so far provided 11 gravitational-wave (GW) observations of black-hole binaries. Similar detections are bound to become very frequent in the near future. With
Constraints on primordial black holes
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 are updated and even if PBHs make a small contribution to the DM, they could play an important cosmological role and provide a unique probe of the early Universe.
