Dark Energy
Sergio Luigi Cacciatori, Vittorio Gorini, Federico Re
Among the great mysteries that physics has not yet solved are undoubtedly those of dark energy and dark matter. In this chapter we deal with the first of them. We will expound in d…
Dark Matter
Sergio Luigi Cacciatori, Vittorio Gorini, Federico Re
In this article we address the mystery of dark matter. We expound the various evidences, astrophysical and cosmological, leading to hypothesize the existence of an invisible form o…
Effective galactic dark matter: first order general relativistic corrections
Federico Re, Marco Galoppo
Stationary, axisymmetric, dust sourced solutions of Einstein's equations have been proposed as fully general relativistic models for disc galaxies. These models introduce a novel p…
Structure of the equivalent Newtonian systems in MOND N-body simulations. Density profiles and the core-cusp problem
Federico Re, Pierfrancesco Di Cintio
We investigate the core-cusp problem of the cold dark matter (CDM) scenario in the context of Modified Newtonian Dynamics (MOND) paradigm exploiting the concept of equivalen…
Re-weighting dark matter in disc galaxies: a new general relativistic observational test
Davide Astesiano, Sergio L. Cacciatori, Massimo Dotti +2
A recent analysis of data from the ESA Gaia mission demonstrated that the kinematics of stars in the Milky Way can be modelled without invoking the presence of dark matter whatsoev…
Towards a full general relativistic approach to galaxies
Davide Astesiano, Sergio L. Cacciatori, Federico Re
We analyze the dynamics of a single spiral galaxy from a general relativistic viewpoint. We employ the known family of stationary axially-symmetric solutions to Einstein gravity co…
On Generalized Lemaitre-Tolman-Bondi Metric. Fractal Matter at the end of Matter-Antimatter Recombination
Sergio Cacciatori, Alessio Marrani, Federico Re
Many recent researches have investigated the deviations from the Friedmannian cosmological model, as well as their consequences on unexplained cosmological phenomena, such as dark…
Fake dark matter from retarded distortions
Federico Re
We push ahead the idea developed in [24], that some fraction of the dark matter and the dark energy can be explained as a relativistic effect. The inhomogeneity matter generates gr…
Distortions of Robertson-Walker metric in perturbative cosmology and interpretation as dark matter and cosmological constant
Federico Re
In the last years, we saw more and more attempts to explain dark matter as a general relativistic effect, at least for some fraction. Following this philosophy, we considered the g…
