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
We study whether the signal seen by pulsar timing arrays (PTAs) may originate from
gravitational waves (GWs) induced by large primordial perturbations. Such perturbations …
