P Auclair, D Bacon, T Baker, T Barreiro… - Living Reviews in …, 2023 - Springer
Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

[HTML][HTML] Observational evidence for primordial black holes: A positivist perspective

BJ Carr, S Clesse, J Garcia-Bellido, MRS Hawkins… - Physics Reports, 2024 - Elsevier
We review numerous arguments for primordial black holes (PBHs) based on observational
evidence from a variety of lensing, dynamical, accretion and gravitational-wave effects. This …

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 …

Primordial black holes as dark matter: recent developments

B Carr, F Kühnel - Annual Review of Nuclear and Particle …, 2020 - annualreviews.org
Although the dark matter is usually assumed to be made up of some form of elementary
particle, primordial black holes (PBHs) could also provide some of it. However, various …

What is the source of the PTA GW signal?

J Ellis, M Fairbairn, G Franciolini, G Hütsi, A Iovino… - Physical Review D, 2024 - APS
The most conservative interpretation of the nHz stochastic gravitational wave background
(SGWB) discovered by NANOGrav and other pulsar timing array (PTA) collaborations is …

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 …

First-order phase transition interpretation of pulsar timing array signal is consistent with solar-mass black holes

Y Gouttenoire - Physical Review Letters, 2023 - APS
We perform a Bayesian analysis of NANOGrav 15-yr and IPTA DR2 pulsar timing residuals
and show that the recently detected stochastic gravitational-wave background is compatible …

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) …

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 …
