Scalar induced gravitational waves review

G Domènech - Universe, 2021 - mdpi.com
We provide a review on the state-of-the-art of gravitational waves induced by primordial
fluctuations, so-called induced gravitational waves. We present the intuitive physics behind …

Constraints on primordial black holes

B Carr, K Kohri, Y Sendouda… - Reports on Progress in …, 2021 - iopscience.iop.org
We update the constraints on the fraction of the Universe that may have gone into primordial
black holes (PBHs) over the mass range 10− 5 to 10 50 g. Those smaller than∼ 10 15 g …

Recent gravitational wave observation by pulsar timing arrays and primordial black holes: The importance of non-Gaussianities

G Franciolini, AJ Iovino, V Vaskonen, H Veermäe - Physical Review Letters, 2023 - APS
We study whether the signal seen by pulsar timing arrays (PTAs) may originate from
gravitational waves (GWs) induced by large primordial perturbations. Such perturbations …

NANOGrav data hints at primordial black holes as dark matter

V De Luca, G Franciolini, A Riotto - Physical Review Letters, 2021 - APS
The NANOGrav Collaboration has recently published strong evidence for a stochastic
common-spectrum process that may be interpreted as a stochastic gravitational wave …

Primordial non-Gaussianity up to all orders: Theoretical aspects and implications for primordial black hole models

G Ferrante, G Franciolini, AJ Iovino, A Urbano - Physical Review D, 2023 - APS
We develop an exact formalism for the computation of the abundance of primordial black
holes (PBHs) in the presence of local non-Gaussianity (NG) in the curvature perturbation …

From inflation to black hole mergers and back again: Gravitational-wave data-driven constraints on inflationary scenarios with a first-principle model of primordial black …

G Franciolini, I Musco, P Pani, A Urbano - Physical Review D, 2022 - APS
Recent population studies have searched for a subpopulation of primordial black holes
(PBHs) in the gravitational-wave (GW) events so far detected by LIGO/Virgo/KAGRA (LVK) …

How well do we know the primordial black hole abundance: The crucial role of nonlinearities when approaching the horizon

V De Luca, A Kehagias, A Riotto - Physical Review D, 2023 - APS
We discuss the nonlinear corrections entering in the calculation of the primordial black hole
abundance from the nonlinear radiation transfer function and the determination of the true …

Primordial black holes—perspectives in gravitational wave astronomy

M Sasaki, T Suyama, T Tanaka… - Classical and Quantum …, 2018 - iopscience.iop.org
This article reviews current understanding of primordial black holes (PBHs), with particular
