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…
Towards a new model-independent calibration of Gamma-Ray Bursts
Arianna Favale, Maria Giovanna Dainotti, Adrià Gómez-Valent +1
Current data on baryon acoustic oscillations and Supernovae of Type Ia cover up to . These observations play a very important role in the determination of cosmological p…
