Can the NANOGrav observations constrain the geometry of the universe?

Matteo Califano, Rocco D'Agostino, Daniele Vernieri

The theory of inflation provides an elegant explanation for the nearly flat universe observed today, which represents one of the pillars of the standard cosmological model. However…

Joint estimation of the cosmological model and the mass and redshift distributions of the binary black hole population with the Einstein Telescope

Matteo Califano, Ivan De Martino, Daniele Vernieri

We investigate the capability of constraining the mass and redshift distributions of binary black hole systems jointly with the underlying cosmological model using one year of obse…

Parity violation in gravitational waves and observational bounds from third-generation detectors

Matteo Califano, Rocco D'Agostino, Daniele Vernieri

In this paper, we analyze parity-violating effects in the propagation of gravitational waves (GWs). For this purpose, we adopt a newly proposed parametrized post-Einstenian (PPE) f…

Exploiting the Einstein Telescope to solve the Hubble tension

Matteo Califano, Ivan de Martino, Daniele Vernieri +1

We probe four cosmological models which, potentially, can solve the Hubble tension according to the dark energy equation of state. In this context, we demonstrate that the Einstein…

Role of spatial curvature in the primordial gravitational wave power spectrum

Rocco D'Agostino, Matteo Califano, Nicola Menadeo +1

This paper investigates the effects of nonvanishing spatial curvature on the propagation of primordial gravitational waves produced during inflation. In particular, we consider ten…

New limits on warm inflation from pulsar timing arrays

Rocco D'Agostino, Matteo Califano

In this paper, we investigate scalar-induced gravitational waves (GWs) generated in the post-inflationary universe to infer new limits on warm inflation. We specifically examine th…

Probing Interacting Dark Sector with the next generation of gravitational-wave detectors

Matteo Califano, Ivan De Martino, Ruth Lazkoz

We have probed the capability of third-generation Gravitational Waves (GW) interferometers, such as the Einstein Telescope and Cosmic Explorer, to constrain a cosmological model wi…

The Science of the Einstein Telescope

Adrian Abac, Raul Abramo, Simone Albanesi +485

Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…

Constraining CDM cosmological parameters with Einstein Telescope mock data

Matteo Califano, Ivan de Martino, Daniele Vernieri +1

We investigate the capability of Einstein Telescope to constrain the cosmological parameters of the non-flat CDM cosmological model. Two types of mock datasets are considered d…
