Extended Universal Rotational Curve of Spiral Galaxies
Esha Bhatia, Paolo Salucci, Tiziano Schiavone +1
In this work, we aim to advance the Universal Rotation Curve (URC) paradigm by leveraging new data and extending its observational domain. Building on previous studies that establi…
Revisiting the Matter Creation Process: Observational Constraints on Gravitationally Induced Dark Energy and the Hubble Tension
Tiziano Schiavone, Mariaveronica De Angelis, Luis A. Escamilla +2
The Hubble tension and the unknown origin of dark energy motivate the exploration of alternative mechanisms for late-time cosmic acceleration. We investigate gravitationally induce…
Exponential cosmology with massive neutrinos as a dynamical dark energy framework
Simone D'Onofrio, Sergei Odintsov, Tiziano Schiavone
The exponential gravity model provides a theoretically well-motivated extension of General Relativity, introducing a modified gravitational dynamics at late times consistent…
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.…
Evolution of an effective Hubble constant in modified gravity
Tiziano Schiavone, Giovanni Montani
We investigate the Hubble constant tension within modified gravity in the Jordan frame, focusing on its application to the dynamics of an isotropic Universe. A scalar field,…
The skewness of the distance-redshift relation in CDM
Tiziano Schiavone, Enea Di Dio, Giuseppe Fanizza
Starting from a recently proposed framework for the evaluation of the cosmological averages, we evaluate the higher-order moments for the distribution of a given observable. Then,…
