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…
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…
Comparing the luminosity distance for gravitational waves and electromagnetic signals in a simple model of quadratic gravity
G. Fanizza, G. Franchini, M. Gasperini +1
We compute the modified friction coefficient controlling the propagation of tensor metric perturbations in the context of a generalized cosmological scenario based on a theory of g…
Cutting out the cosmological middle man: General Relativity in the light-cone coordinates
Ermis Mitsou, Giuseppe Fanizza, Nastassia Grimm +1
Analytical computations in relativistic cosmology can be split into two sets: time evolution relating the initial conditions to the observer's light-cone and light propagation to o…
The Cosmological Perturbation Theory on the Geodesic Light-Cone background
Giuseppe Fanizza, Giovanni Marozzi, Matheus Medeiros +1
Inspired by the fully non-linear Geodesic Light-Cone (GLC) gauge, we consider its analogous set of coordinates which describes the unperturbed Universe. Given this starting point,…
