Precision Cosmology and Hubble tension in the era of LSS surveys
Giuseppe Fanizza
We present a fully relativistic framework to evaluate the impact of stochastic inhomogeneities on the prediction of the Hubble-Lemaître diagram. In this regard, we relate the fluct…
Qualitative aspects in nonlocal dynamics
Giuseppe Maria Coclite, Serena Dipierro, Giuseppe Fanizza +3
In this paper we investigate, through numerical studies, the dynamical evolutions encoded in a linear one-dimensional nonlocal equation arising in peridynamcs. The different propag…
Linearized propagation equations for metric fluctuations in a general (non-vacuum) background geometry
G. Fanizza, M. Gasperini, E. Pavone +1
The linearized dynamical equation for metric perturbations in a fully general, non-vacuum, background geometry is obtained from the Hamilton variational principle applied to the ac…
Dispersive effects in a scalar nonlocal wave equation inspired by peridynamics
Giuseppe Maria Coclite, Serena Dipierro, Giuseppe Fanizza +2
We study the dispersive properties of a linear equation in one spatial dimension which is inspired by models in peridynamics. The interplay between nonlocality and dispersion is an…
Cosmic variance of in light of forthcoming high-redshift surveys
Giuseppe Fanizza, Bartolomeo Fiorini, Giovanni Marozzi
Forthcoming surveys will extend the understanding of cosmological large scale structures up to unprecedented redshift. According to this perspective, we present a fully relativisti…
