Large fluctuations and primordial black holes
In this paper, we review in detail different mechanisms of generation of large primordial
fluctuations and their implications for the production of primordial black holes (PBHs) and …

Galileon inflation evades the no-go for PBH formation in the single-field framework
We consider Galileon inflation in the Effective Field Theory (EFT) framework and examine
the possibility for PBH formation during slow roll (SR) to ultra slow roll (USR) transitions. We …

Inflation, the Hubble tension, and early dark energy: An alternative overview
I review and discuss the possible implications for inflation resulting from considering new
physics in light of the Hubble tension. My study is motivated by a simple argument that the …

[HTML][HTML] Primordial non-Gaussianity as a saviour for PBH overproduction in SIGWs generated by Pulsar Timing Arrays for Galileon inflation
We investigate the explicit role of negative local non-Gaussianity, f NL, in suppressing the
abundance of primordial black holes (PBHs) in the single-field model of Galileon inflation …

Primordial black holes from single-field inflation: a fine-tuning audit
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 …

Realisation of the ultra-slow roll phase in Galileon inflation andPBH overproduction
We demonstrate the explicit realisation of the ultra-slow roll phase in the framework of the
effective field theory of single-field Galileon inflation. The pulsar timing array (PTA) …

Primordial perturbations from ultra-slow-roll single-field inflation with quantum loop effects
SL Cheng, DS Lee, KW Ng - Journal of Cosmology and …, 2024 - iopscience.iop.org
It is known that the single-field inflation with a transient ultra-slow-roll phase can produce a
large curvature perturbation at small scales for the formation of primordial black holes. In our …

Primordial black holes as dark matter: interferometric tests of phase transition origin
A bstract We show that primordial black holes—in the observationally allowed mass window
with f PBH= 1—formed from late nucleating patches in a first order phase transition imply …

Multi-field inflation with large scalar fluctuations: non-Gaussianity and perturbativity
Recently multi-field inflation models that can produce large scalar fluctuations on small
scales have drawn a lot of attention, primarily because they could lead to primordial black …
