Neutrino Mass Bounds in the era of Tension Cosmology
Eleonora Di Valentino, Alessandro Melchiorri
The measurements of Cosmic Microwave Background anisotropies made by the Planck satellite provide extremely tight upper bounds on the total neutrino mass scale ( at $…
Testing spatial curvature and anisotropic expansion on top of the CDM model
Ozgur Akarsu, Eleonora Di Valentino, Suresh Kumar +2
We explore the possible advantages of extending the CDM model by more realistic backgrounds compared to its spatially flat RW spacetime assumption, while preserving the underpin…
Cosmological constraints on slow-roll inflation: an update
Matteo Forconi, William Giarè, Eleonora Di Valentino +1
In light of the most recent cosmological observations, we provide new updated constraints on the slow-roll inflation in different extended scenarios beyond the cosmolog…
Late time interacting cosmologies and the Hubble constant tension
Stefano Gariazzo, Eleonora Di Valentino, Olga Mena +1
In this manuscript we reassess the potential of interacting dark matter-dark energy models in solving the Hubble constant tension. These models have been proposed but also question…
Late-transition vs smooth deformation models for the resolution of the Hubble crisis
George Alestas, David Camarena, Eleonora Di Valentino +4
Gravitational transitions at low redshifts () have been recently proposed as a solution to the Hubble and growth tensions. Such transitions would naturally lead to a trans…
Minimal dark energy: key to sterile neutrino and Hubble constant tensions?
Eleonora Di Valentino, Stefano Gariazzo, Carlo Giunti +3
Minimal dark energy models, described by the same number of free parameters of the standard cosmological model with cold dark matter plus a cosmological constant to parameterize th…
Cosmological forecasts on thermal axions, relic neutrinos and light elements
William Giarè, Fabrizio Renzi, Alessandro Melchiorri +2
One of the targets of future Cosmic Microwave Background and Baryon Acoustic Oscillation measurements is to improve the current accuracy in the neutrino sector and reach a much bet…
Constraints from High-Precision Measurements of the Cosmic Microwave Background: The Case of Disintegrating Dark Matter with or Dynamical Dark Energy
Wenzhong Liu, Luis A. Anchordoqui, Eleonora Di Valentino +3
In recent years discrepancies have emerged in measurements of the present-day rate of expansion of the universe and in estimates of the clustering of matter . Using the…
Dissecting the and tensions with Planck + BAO + supernova type Ia in multi-parameter cosmologies
Luis A. Anchordoqui, Eleonora Di Valentino, Supriya Pan +1
The mismatch between the locally measured expansion rate of the universe and the one inferred from observations of the cosmic microwave background (CMB) assuming the canonical C…
Teleparallel Gravity: From Theory to Cosmology
Sebastian Bahamonde, Konstantinos F. Dialektopoulos, Celia Escamilla-Rivera +7
Teleparallel gravity has significantly increased in popularity in recent decades, bringing attention to Einstein's other theory of gravity. In this Review, we relate this form of g…
Dark Energy Survey Year 3 Results: Cosmological Constraints from Galaxy Clustering and Weak Lensing
DES Collaboration, T. M. C. Abbott, M. Aguena +168
We present the first cosmology results from large-scale structure in the Dark Energy Survey (DES) spanning 5000 deg. We perform an analysis combining three two-point correlatio…
Modified Gravity and Cosmology: An Update by the CANTATA Network
Emmanuel N. Saridakis, Ruth Lazkoz, Vincenzo Salzano +50
General Relativity and the CDM framework are currently the standard lore and constitute the concordance paradigm. Nevertheless, long-standing open theoretical issues, as well as…
