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.…

Exploring new physics in the late Universe's expansion through non-parametric inference

Miguel A. Sabogal, Özgür Akarsu, Alexander Bonilla +2

In this study, we investigate deviations from the Planck-CDM model in the late universe () using the Gaussian Processes method, with minimal assumptions. Our goa…

Inferring and with cosmic growth rate measurements using machine learning

Felipe Avila, Armando Bernui, Alexander Bonilla +1

Measurements of the cosmological parameter provided by cosmic microwave background and large scale structure data reveal some tension between them, suggesting that the cluste…
