Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

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 …

Abstract The Einstein Telescope (ET), the European project for a third-generation
gravitational-wave detector, has a reference configuration based on a triangular shape …

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

The most conservative interpretation of the nHz stochastic gravitational wave background
(SGWB) discovered by NANOGrav and other pulsar timing array (PTA) collaborations is …

The third Gravitational-Wave Transient Catalog (GWTC-3) describes signals detected with
Advanced LIGO and Advanced Virgo up to the end of their third observing run. Updating the …

We report on the population properties of compact binary mergers inferred from gravitational-
wave observations of these systems during the first three LIGO-Virgo observing runs. The …

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) …

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 …

Population-synthesis codes are an unique tool to explore the parameter space of massive
binary star evolution and binary compact object (BCO) formation. Most population-synthesis …
