The asymmetry of dawn: evidence for asymmetric reionization histories from a joint analysis of cosmic microwave background and astrophysical data

Autor: Paoletti, Daniela, Hazra, Dhiraj Kumar, Finelli, Fabio, Smoot, George F.

We show that by jointly fitting cosmic microwave background (CMB) and astrophysical data - a compilation of UV luminosity data from the Hubble Frontier Field and neutral hydrogen data from distant sources-, we can infer on the shape of the evolution

The quest of CMB spectral distortions to probe the scalar-induced gravitational wave background interpretation in PTA data

Autor: Tagliazucchi, Matteo, Braglia, Matteo, Finelli, Fabio, Pieroni, Mauro

Gravitational Waves (GW) sourced by second-order primordial curvature fluctuations are among the favoured models fitting the recent Pulsar Timing Array (PTA) measurement of a Stochastic GW Background (SGWB). We study how spectral distortions (SDs) an

Redshift evolution of cosmic birefringence in CMB anisotropies

Autor: Galaverni, Matteo, Finelli, Fabio, Paoletti, Daniela

We study the imprints of a cosmological redshift-dependent pseudoscalar field $\phi$ on the rotation of cosmic microwave background (CMB) linear polarization generated by a coupling $ \phi F^{\mu\nu} \tilde F_{\mu \nu}$. We show how either phenomenol

Planck and BICEP/Keck Array 2018 constraints on primordial gravitational waves and perspectives for future B-mode polarization measurements

Autor: Paoletti, Daniela, Finelli, Fabio, Valiviita, Jussi, Hazumi, Masashi

Current and future B-mode polarization data are the most powerful observables to constrain gravitational waves from the early Universe. We set conservative constraints on tensor modes when relaxing the inflationary consistency condition $n_t=-r/8$ be

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 $
