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…
