One-loop power spectrum corrections in interacting dark energy cosmologies
Emanuelly Silva, Gabriel Hartmann, Rafael C. Nunes
Interacting Dark Energy (IDE) models offer a promising avenue to explore possible exchanges of energy and momentum between dark matter and dark energy, providing a dynamical extens…
Testing signatures of phantom crossing through full-shape galaxy clustering analysis
Emanuelly Silva, Rafael C. Nunes
Recent observations of baryon acoustic oscillations (BAO) from the Dark Energy Spectroscopic Instrument (DESI) survey, when combined with measurements of the cosmic microwave backg…
Robust Evidence for Dynamical Dark Energy from DESI Galaxy-CMB Lensing Cross-Correlation and Geometric Probes
Miguel A. Sabogal, Rafael C. Nunes
Recent analyses joining data from the Cosmic Microwave Background (CMB), Baryon Acoustic Oscillations (BAO), and Type Ia Supernovae (SNIa) have provided strong evidence in favor of…
Challenging CDM: 5 Evidence for a Dynamical Dark Energy Late-Time Transition
Mateus Scherer, Miguel A. Sabogal, Rafael C. Nunes +1
Recently, there has been considerable debate regarding potential evidence for the dynamical nature of dark energy (DE), particularly in light of Baryon Acoustic Oscillations (BAO)…
Updated Constraints on Omnipotent Dark Energy: A Comprehensive Analysis with CMB and BAO Data
Enrico Specogna, Shahnawaz A. Adil, Emre Ozulker +4
In this work, we present updated observational constraints on the parameter space of the DMS20 dark energy model, a member of the omnipotent dark energy (ODE) class. Our analysis c…
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.…
New constraints on interacting dark energy from DESI DR2 BAO observations
Emanuelly Silva, Miguel A. Sabogal, Mateus Scherer +3
In its second data release (DR2), the Dark Energy Spectroscopic Instrument (DESI) publicly released measurements of Baryon Acoustic Oscillations (BAO) from over 13.1 million galaxi…
Sign Switching in Dark Sector Coupling Interactions as a Candidate for Resolving Cosmological Tensions
Miguel A. Sabogal, Emanuelly Silva, Rafael C. Nunes +2
The CDM model has successfully explained a wide range of cosmological observations, but is increasingly challenged by the emergence of cosmological tensions, particularly the Hu…
Mapping the CDM scenario to modified gravity: Effects on structure growth rate
Mateus S. Souza, Ana M. Barcelos, Rafael C. Nunes +2
The concept of a rapidly sign-switching cosmological constant, interpreted as a mirror AdS-dS transition in the late universe and known as the CDM, has significantly imp…
