Mechanisms for producing Primordial Black Holes from Inflationary Models Beyond Fine-Tuning
Ioanna Stamou
In this study, we present an analysis of the fine-tuning required in various inflationary models in order to explain the production of Primordial Black Holes (PBHs). We specificall…
Reconstructing Primordial Black Hole Power Spectra from Gravitational Waves
Daniel Frolovsky, Florian Kuhnel, Ioanna Stamou
A novel methodology for analysing the relation between the energy density in gravitational waves and primordial power spectra is developed. Focusing on scalar-induced gravitational…
Large curvature fluctuations from no-scale supergravity with a spectator field
Ioanna D. Stamou
We investigate the large curvature perturbations which can lead to the formation of primordial black holes (PBHs) in the context of no-scale supergravity. Our study does not depend…
Can Primordial Black Holes form in the Standard Model ?
Ioanna Stamou, Sebastien Clesse
We investigate the viability of primordial black hole (PBH) formation in the Standard Model (SM) in a scenario that does not rely on specific inflationary features or any exotic ph…
Primordial Black Holes without fine-tuning from a light stochastic spectator field
Ioanna Stamou, Sebastien Clesse
We investigate a mechanism of primordial black hole (PBH) formation that avoids any dependence on specific inflationary features or exotic physics. In this scenario, the required l…
Mechanisms of Producing Primordial Black Holes By Breaking The SU(2,1)/SU(2)U(1) Symmetry
Ioanna D. Stamou
In this paper we present a class of potentials derived by no-scale supergravity in order to explain the production of primordial black holes (PBHs) in the Universe. By breaking the…
