Multidimensionality of the Hubble tension: the roles of and
Davide Pedrotti, Jun-Qian Jiang, Luis A. Escamilla +2
The Hubble tension is inherently multidimensional, and bears important implications for parameters beyond . We discuss the key role of the matter density parameter and t…
Nonparametric late-time expansion history reconstruction and implications for the Hubble tension in light of recent DESI and type Ia supernovae data
Jun-Qian Jiang, Davide Pedrotti, Simony Santos da Costa +1
We nonparametrically reconstruct the late-time expansion history in light of the latest Baryon Acoustic Oscillation (BAO) measurements from DESI combined with various Type Ia Super…
Gauge invariant quantum backreaction in U(1) axion inflation
Davide Campanella Galanti, Pietro Conzinu, Giovanni Marozzi +1
We evaluate the quantum backreaction due to a gauge field coupled to a pseudo-scalar field driving a slow-roll inflationary stage, the so-called axion inflation. The backreaction i…
Observational constraints on -attractor inflationary models with a Higgs-like potential
J. G. Rodrigues, S. Santos da Costa, J. S. Alcaniz
We investigate the observational viability of a class of -attractors inflationary models in light of the most recent Cosmic Microwave Background (CMB) and Large-Scale Structure…
Brane inflation and the robustness of the Starobinsky inflationary model
S. Santos da Costa, M. Benetti, R. M. P. Neves +3
The first inflationary model conceived was the one proposed by Starobinsky which includes an additional term quadratic in the Ricci-scalar R in the Einstein-Hilbert action. The mod…
