-CDM: A promising phenomenological extension of the standard model of cosmology
Suresh Kumar
We investigate a phenomenological extension of the standard CDM framework, the -CDM model, in which the total energy density of the universe is expanded in powers of…
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…
