Exploring Modified Gravity: Constraints on the and Parametrization with WMAP, ACT, and SPT
Uendert Andrade, Abraão J. S. Capistrano, Eleonora Di Valentino +1
The cosmic acceleration problem remains one of the most significant challenges in cosmology. One of the proposed solutions to this problem is the modification of gravity on large s…
Cosmographic view on the and tensions
Rocco D'Agostino, Rafael C. Nunes
Measurements of the and parameters within the standard cosmological model recently highlighted significant statistical tensions between the cosmic microwave background…
CDM model: A promising scenario for alleviation of cosmological tensions
Ozgur Akarsu, Eleonora Di Valentino, Suresh Kumar +3
We present a comprehensive analysis of the CDM model, which explores the recent conjecture suggesting a rapid transition of the Universe from anti-de Sitter vacua to de…
The state of the dark energy equation of state circa 2023
Luis A. Escamilla, William Giarè, Eleonora Di Valentino +2
We critically examine the state of current constraints on the dark energy (DE) equation of state (EoS) . Our study is motivated by the observation that, while broadly consistent…
Omnipotent dark energy: A phenomenological answer to the Hubble tension
Shahnawaz A. Adil, Ozgur Akarsu, Eleonora Di Valentino +4
This paper introduces the class of omnipotent dark energy (DE) models characterized by nonmonotonic energy densities that are capable of attaining negative values with correspondin…
A Consistent View of Interacting Dark Energy from Multiple CMB Probes
Yuejia Zhai, William Giarè, Carsten van de Bruck +3
We analyze a cosmological model featuring an interaction between dark energy and dark matter in light of the measurements of the Cosmic Microwave Background released by three indep…
New late-time constraints on gravity
Suresh Kumar, Rafael C. Nunes, Supriya Pan +1
Modification of general relativity (GR) inspired by theories like gravity is among the most popular ones to explain the late-time acceleration of the Universe as an alternat…
Exploring the tension and the evidence of dark sector interaction from 2D BAO measurements
Armando Bernui, Eleonora Di Valentino, William Giarè +2
We explore observational constraints on a cosmological model with an interaction between dark energy (DE) and dark matter (DM), using a compilation of 15 measurements of the 2D BAO…
