Beyond ÎCDM with the SKA Observatory -- I: Probing Gravity on Cosmological Scales
S. Camera, C. Addis, S. L. Guedezounme +26
General relativity (GR) is currently the best description of the gravitational interaction at our disposal and is one of the foundations of the concordance cosmological model. For…
How deep can a cosmic void be? Voids-informed theoretical bounds in Galileon gravity
Tommaso Moretti, Noemi Frusciante, Giovanni Verza +1
We establish a void-based consistency test for Galileon scalar-tensor theories. We show that the previously reported unphysical breakdown of the predicted Newtonian force in certai…
Cosmic voids evolution in modified gravity via hydrodynamics
Tommaso Moretti, Noemi Frusciante, Giovanni Verza +1
We present a hydrodynamical description of isolated spherical voids in modified gravity (MG), extending the standard General Relativity (GR) and dynamical dark energy treatment by…
A spherical hydrodynamical model of cosmic voids in ÎCDM and beyond
Tommaso Moretti, Giovanni Verza, Noemi Frusciante +1
Cosmic voids have emerged as powerful probes for cosmology, providing complementary information on the large-scale structure of the universe. We present the first application of a…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
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.…
