A Periodically Interacting Dark Sector: Signatures and Constraints from CMB and Cosmic Expansion Data
Marco Antonio Cardoso Alvarez, Micol Benetti, Leila Graef +1
The paper proposes a cosmological model where the interaction between dark matter and dark energy oscillates in sign over time, representing the back‑reaction of super‑Hubble fluct…
Extended Theories of Electrodynamics in Gravity
Francesco Bajardi, Micol Benetti, Salvatore Capozziello +1
Within the general framework of gravity, we introduce a function of the electromagnetic curvature invariant that couples minimally to gravitation to ensure a…
Constraining a de Broglie--Bohm quantum bounce cosmology with Planck data
Micol Benetti, Rudnei O. Ramos, Renato Silva +1
This work investigates a singularity-free early Universe within the paradigm of quantum cosmology. We develop a bouncing model where the singularity is resolved via the de Broglie-…
Can cosmic rotation resolve the Hubble tension? Constraints from CMB and large-scale structure
Micol Benetti, David A. Cook, Saulo Carneiro
We investigate a relativistic cosmological model with background rotation, sourced by a non-perfect fluid with anisotropic stress. A modified version of the CLASS Boltzmann code is…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Quasar cosmology II: joint analyses with Cosmic Microwave Background
M. Benetti, G. Bargiacchi, G. Risaliti +3
Currently, the increasing availability of accurate cosmological probes leads to the emergence of tensions between data on the one hand and between theoretical predictions and direc…
