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 …

Footprints of the QCD crossover on cosmological gravitational waves at pulsar timing arrays

G Franciolini, D Racco, F Rompineve - Physical Review Letters, 2024 - APS
Pulsar timing arrays (PTAs) have reported evidence for a stochastic gravitational wave (GW)
background at nanohertz frequencies, possibly originating in the early Universe. We show …

Implications for the non-Gaussianity of curvature perturbation from pulsar timing arrays

L Liu, ZC Chen, QG Huang - Physical Review D, 2024 - APS
The recently released data by pulsar timing array (PTA) collaborations present strong
evidence for a stochastic signal consistent with a gravitational-wave background. Assuming …

Scalar-induced gravitational wave interpretation of PTA data: the role of scalar fluctuation propagation speed

S Balaji, G Domènech… - Journal of Cosmology and …, 2023 - iopscience.iop.org
Pulsar timing arrays gathered evidence of the presence of a gravitational wave background
around nHz frequencies. If the gravitational wave background was induced by large and …

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 …

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 …
