Constraining the impact of standard model phase transitions on primordial black holes
Xavier Pritchard, Christian T. Byrnes
Phase transitions in the early universe lead to a reduction in the equation of state of the primordial plasma. This exponentially enhances the formation rate of primordial black ho…
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…
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…
Lecture notes on inflation and primordial black holes
Christian T. Byrnes, Philippa S. Cole
These lecture notes are based on those presented at the Theoretical Aspects of Astroparticle Physics, Cosmology and Gravitation School at the Galileo Galilee Institute in Florence…
EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade
R. Alves Batista, M. A. Amin, G. Barenboim +134
Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…
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…
