Third-order corrections to the slow-roll expansion: calculation and constraints with Planck, ACT, SPT, and BICEP/Keck

Autor: Ballardini, Mario, Davoli, Alessandro, Sirletti, Salvatore Samuele

We investigate the primordial power spectra (PPS) of scalar and tensor perturbations, derived through the slow-roll approximation. By solving the Mukhanov-Sasaki equation and the tensor perturbation equation with Green's function techniques, we exten

Probing Early Modification of Gravity with Planck, ACT and SPT

Autor: Abellán, Guillermo Franco, Braglia, Matteo, Ballardini, Mario, Finelli, Fabio, Poulin, Vivian

Publikováno v: JCAP 12 (2023) 017

We consider a model of early modified gravity (EMG) that was recently proposed as a candidate to resolve the Hubble tension. The model consists in a scalar field $\sigma$ with a non-minimal coupling (NMC) to the Ricci curvature of the form $F(\sigma)

Cosmic Probes of Fundamental Physics take two primary forms: Very high energy particles (cosmic rays, neutrinos, and gamma rays) and gravitational waves. Already today, these probes give access to fundamental physics not available by any other means,

In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological probes, such as the disagreement in the value of the Hubble constant $

Type Ia supernovae data with scalar-tensor gravity

Autor: Ballardini, Mario, Finelli, Fabio

We study the use of type Ia supernovae (SNe Ia) in the context of scalar-tensor theories of gravity, taking as a working example induced gravity, equivalent to Jordan-Brans-Dicke theory. Winking at accurate and precision cosmology, we test the correc
