Revisiting model-independent constraints on spatial curvature and cosmic ladders calibration: updated and forecast analyses

Arianna Favale, Adrià Gómez-Valent, Marina Migliaccio

Model-independent approaches have gained increasing attention as powerful tools to investigate persistent tensions between cosmological observations and the predictions of CDM.…

Revisiting Gaussian Process Reconstruction for Cosmological Inference: The Generalised GP (Gen GP) Framework

Ruchika, Purba Mukherjee, Arianna Favale

We investigate uncertainties in the estimation of the Hubble constant () arising from Gaussian Process (GP) reconstruction, demonstrating that the choice of kernel introduces…

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.…

Illustrating the consequences of a misuse of in cosmology

Matteo Forconi, Arianna Favale, Adrià Gómez-Valent

The parameter is the rms mass fluctuations on a scale of Mpc and is used to quantify the amplitude of matter fluctuations at linear scales. However, the depend…
