Scalar-tensor theories of gravity, neutrino physics, and the H0 tension
(IOP Publishing, 2020)
We use Planck 2018 data to constrain the simplest models of scalar-tensor theories
characterized by a coupling to the Ricci scalar of the type F(σ)R with F(σ) = N2

We update our results with previous Planck ...
Measuring lensing ratios with future cosmological surveys
(American Physical Society, 2020)
The ratio between the CMB lensing/galaxy counts and the galaxy shear/galaxy counts cross-correlations combines the information from different cosmological probes to infer cosmographic measurements that are less dependent ...
On the primordial origin of the smoothing excess in the Planck temperature power spectrum in light of LSS data
(IOP Publishing, 2022)
The Planck DR3 measurements of the temperature and polarization anisotropies power spectra of the cosmic microwave background (CMB) show an excess of smoothing of the acoustic peaks with respect to ΛCDM, often quantified ...
