Journal ArticleDOI
The importance of priors on LIGO-Virgo parameter estimation: the case of primordial black holes
TL;DR: In this paper, the authors show that incorporating these priors can significantly change the inferred mass ratio and effective spin of some binary black hole events, especially those identified as high-mass, asymmetrical, or spinning by a standard analysis using agnostic priors.
Journal ArticleDOI
Gravitational Wave Anisotropies from Primordial Black Holes
N. Bartolo,Daniele Bertacca,V. De Luca,Gabriele Franciolini,Sabino Matarrese,Marco Peloso,Angelo Ricciardone,Antonio Riotto,Gianmassimo Tasinato +8 more
TL;DR: In this paper, the anisotropies and non-Gaussianity of a stochastic background of the early universe were calculated. And they were shown that a sizeable magnitude of anisotropy in the gravitational waves would suggest that primordial black holes may not comply the totality of the dark matter.
Journal ArticleDOI
Non-Gaussianity from Inflation: Theory and Observations
TL;DR: A review of models of inflation and their predictions for the primordial non-Gaussianity in the density perturbations which are thought to be at the origin of structures in the Universe is given in this paper.
Journal ArticleDOI
The clockwork supergravity
Alex Kehagias,Antonio Riotto +1 more
TL;DR: In this article, it was shown that the minimal D = 5, $$ \mathcal{N} $$ = 2 gauged supergravity set-up may encode naturally the recently proposed clockwork mechanism.
Journal ArticleDOI
Primordial Black Holes from Inflation and Quantum Diffusion
TL;DR: In this paper, the authors argue that quantum diffusion has a significant impact on the primordial black hole mass fraction making the classical standard prediction not trustable, and propose a quantum diffusion-based single-field model of black hole creation.
