A Periodically Interacting Dark Sector: Signatures and Constraints from CMB and Cosmic Expansion Data
Marco Antonio Cardoso Alvarez, Micol Benetti, Leila Graef +1
We introduce a novel cosmological model that provides an effective description of the back-reaction of super-Hubble fluctuations on the cosmological background, a generic effect ex…
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…
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…
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.…
Dark sector interactions in light of weak lensing data
M. Benetti, P. T. Z. Seidel, C. Pigozzo +3
The current observational tensions in the standard cosmological model have reinforced the research on dynamical dark energy, in particular on models with non-gravitational interact…
A visual tool for assessing tension-resolving models in the - plane
Igor de O. C. Pedreira, Micol Benetti, Elisa G. M. Ferreira +2
Beyond-CDM models have been proposed to address various shortcomings of the standard cosmological model, such as the ``Hubble tension.'' These models often have an impact on the…
Beyond CDM with CDM: criticalities and solutions of Padé Cosmography
Alexandra T. Petreca, Micol Benetti, Salvatore Capozziello
Recently, cosmography emerged as a valuable tool to effectively describe the vast amount of astrophysical observations without relying on a specific cosmological model. Its model-i…
Testing the growth rate in homogeneous and inhomogeneous interacting vacuum models
H. A. Borges, C. Pigozzo, P. Hepp +2
In this work we consider a class of interacting vacuum corresponding to a generalised Chaplygin gas (gCg) cosmology. In particular we analyse two different scenarios at perturbatio…
Higgs Inflation: constraining the top quark mass and breaking the - correlation
Jamerson G. Rodrigues, Micol Benetti, Rayff de Souza +1
Extending previous results [JHEP 11 (2021) 091], we explore aspects of the reheating mechanism for non-minimal Higgs inflation in the strong coupling regime. We constrain the radia…
Cosmological constraints on unimodular gravity models with diffusion
Susana J. Landau, Micol Benetti, Alejandro Perez +1
A discrete space-time structure lying at about the Planck scale may become manifest in the form of very small violations of the conservation of the matter energy-momentum tensor. I…
An empirical investigation into cosmological tensions
Ramon de Sá, Micol Benetti, Leila Lobato Graef
The possibility that the tension is a sign of a physics beyond the CDM model is one of the most exciting possibilities in modern cosmology. The challenge of solving this p…
Warm -exponential inflation and the Swampland Conjectures
F. B. M. dos Santos, R. Silva, S. Santos da Costa +2
We investigate theoretical and observational aspects of a warm inflation scenario driven by the -exponential potential, which generalizes the well-known power law inflation. In…
Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies
Elcio Abdalla, Guillermo Franco Abellán, Amin Aboubrahim +200
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…
Primordial gravitational waves from NANOGrav: a broken power-law approach
Micol Benetti, Leila Lobato Graef, Sunny Vagnozzi
We revisit the possibility that the stochastic common-spectrum process recently detected by the NANOGrav pulsar timing array experiment could be due to primordial gravitational wav…
Quasar cosmology: dark energy evolution and spatial curvature

We analyse some open debates in cosmology in light of the most updated quasar (QSO) sample, covering a wide redshift range up to , combined with type Ia supernovae (SNe)…
Constraining non-minimally coupled -exponential inflation with CMB data
Felipe Bruno Medeiros dos Santos, Simony Santos da Costa, Raimundo Silva +2
The -exponential inflation is driven by a class of primordial potentials, derived in the framework of braneworld scenarios, that generalizes the well-known power law inflation.…
Testing the consistency between cosmological data: the impact of spatial curvature and the dark energy EoS
Javier E. Gonzalez, Micol Benetti, Rodrigo von Marttens +1
The results of joint analyses of available cosmological data have motivated an important debate about a possible detection of a non-zero spatial curvature. If confirmed, such a res…
