Updated Cosmological Constraints from 2D BAO Measurements: A New Compilation and Comparison with DESI DR2
Miguel A. Sabogal, Rafael C. Nunes, Felipe Avila +1
We investigate and update observational constraints on cosmological parameters within the CDM and dynamical dark energy frameworks, using a new compilation of the transverse (or…
High-redshift transverse BAO measurements with the SDSS quasar catalog
Felipe Avila, Armando Bernui, Miguel A. Sabogal +1
Transverse Baryon Acoustic Oscillation (BAO) measurements offer a robust geometric probe of the Universe expansion, presenting minimal dependence on fiducial cosmological models. I…
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)…
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…
