Can cosmic voids ease the Hubble tension? Local expansion in CDM
Tommaso Moretti, Noemi Frusciante, Giovanni Verza
We investigate the effect of local cosmic voids on low-redshift measurements of the Hubble rate in flat CDM cosmologies. Using a hydrodynamical model for isolated spherical…
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…
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…
A spherical hydrodynamical model of cosmic voids in ΛCDM 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…
Breaking parity: the case of the trispectrum from chiral scalar-tensor theories of gravity
Tommaso Moretti, Nicola Bartolo, Alessandro Greco
Recently, possible hints of parity violation have been observed in the connected galaxy four-point correlation function. Although the true origin of the signal from the analysis ha…
