Probing Cosmic Expansion and Early Universe with Einstein Telescope

Angelo Ricciardone, Mairi Sakellariadou, Archisman Ghosh +52

Over the next two decades, gravitational-wave (GW) observations are expected to evolve from a discovery-driven endeavour into a precision tool for astrophysics, cosmology, and fund…

From the Solar System to cosmological distances: a complete formalism for gravitational wave astrometry

Gabriele Perna, Nicola Bellomo, Vincenzo Roatti +1

The presence of a gravitational wave background (GWB) can be established not only via exquisitely precise pulsar timing array (PTA) measurements, but also via astrometric observati…

Understanding the Nature of Scalar-Induced Gravitational Waves

A. J. Iovino, G. Perna, D. Perrone +2

We offer a physical interpretation of the origin of the scalar-induced gravitational wave background, showing that it is mainly produced around the peaks of the scalar perturbation…

The Irrelevance of Primordial Black Hole Clustering in the LVK mass range

F. Crescimbeni, V. Desjacques, G. Franciolini +6

We show that in realistic models where primordial black holes are formed due to the collapse of sizeable inflationary perturbations, their initial spatial clustering beyond Poisson…

Reconstructing Primordial Curvature Perturbations via Scalar-Induced Gravitational Waves with LISA

Jonas El Gammal, Aya Ghaleb, Gabriele Franciolini +17

Many early universe scenarios predict an enhancement of scalar perturbations at scales currently unconstrained by cosmological probes. These perturbations source gravitational wave…

How Well Do We Know the Scalar-Induced Gravitational Waves?

A. J. Iovino, S. Matarrese, G. Perna +2

Gravitational waves sourced by amplified scalar perturbations are a common prediction across a wide range of cosmological models. These scalar curvature fluctuations are inherently…
