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…
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…
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…
