Primordial black holes from a curvaton scenario with strongly non-Gaussian perturbations
Andrew D. Gow, Tays Miranda, Sami Nurmi
We investigate the production of primordial black holes (PBHs) in a mixed inflaton-curvaton scenario with a quadratic curvaton potential, assuming the curvaton is in de Sitter equi…
Primordial black holes from single-field inflation: a fine-tuning audit
Philippa S. Cole, Andrew D. Gow, Christian T. Byrnes +1
All single-field inflationary models invoke varying degrees of tuning in order to account for cosmological observations. Mechanisms that generate primordial black holes (PBHs) from…
Non-perturbative non-Gaussianity and primordial black holes
Andrew D. Gow, Hooshyar Assadullahi, Joseph H. P. Jackson +3
We present a non-perturbative method for calculating the abundance of primordial black holes given an arbitrary one-point probability distribution function for the primordial curva…
Smooth vs instant inflationary transitions: steepest growth re-examined and primordial black holes
Philippa S. Cole, Andrew D. Gow, Christian T. Byrnes +1
Primordial black holes (PBHs) can be produced by a range of mechanisms in the early universe. A particular formation channel that connects PBHs with inflationary phenomenology invo…
An accurate model for the primordial black hole mass distribution from a peak in the power spectrum
Andrew D. Gow, Christian T. Byrnes, Alex Hall
We examine the shape of the primordial black hole mass distribution arising from a peak in the primordial power spectrum. In light of improvements to the modelling, we revisit the…
Bayesian analysis of LIGO-Virgo mergers: Primordial vs. astrophysical black hole populations
Alex Hall, Andrew D. Gow, Christian T. Byrnes
We conduct a thorough Bayesian analysis of the possibility that the black hole merger events seen in gravitational waves are primordial black hole (PBH) mergers. Using the latest m…
The power spectrum on small scales: Robust constraints and comparing PBH methodologies
Andrew D. Gow, Christian T. Byrnes, Philippa S. Cole +1
We compare primordial black hole (PBH) constraints on the power spectrum and mass distributions using the traditional Press Schechter formalism, peaks theory, and a recently develo…
Primordial black hole merger rates: distributions for multiple LIGO observables
Andrew D. Gow, Christian T. Byrnes, Alex Hall +1
We have calculated the detectable merger rate of primordial black holes, as a function of the redshift, as well as the binary's mass ratio, total mass and chirp mass (observables t…
