Non-trivial boundary conditions in general-relativistic models
Davide Astesiano, Matteo Luca Ruggiero, Federico Re
We propose an alternative interpretation of dark matter effects within the framework of General Relativity. In particular, we suggest that, in astrophysical and cosmological contex…
A Machian Approach to Relativistic Cosmology
Enrico Massa, Davide Astesiano
We present a consistent relativistic formulation of Mach principle within a geometric theory of gravitation. In this approach, neither inertia nor free fall is assumed a priori. In…
Gravitational lensing observables in stationary and axisymmetric solutions in general relativity
Matteo Luca Ruggiero, Davide Astesiano
We investigate light propagation in self-gravitating systems composed of an axially symmetric, stationary, rotating dust fluid. These configurations are intrinsically relativistic,…
On the low-energy limit of stationary and axisymmetric solutions in General Relativity
Davide Astesiano, Matteo Luca Ruggiero
We study the low-energy limit of General Relativity in the presence of stationarity and axial symmetry, coupled to dust. Specifically, we demonstrate that differences between the d…
Particle motion in a rotating dust spacetime: the Bonnor solution
Davide Astesiano, Donato Bini, Andrea Geralico +1
We investigate the geometrical properties, spectral classification, geodesics, and causal structure of the Bonnor's spacetime [Journal of Physics A Math. Gen., \textbf{10}, 1673 (1…
A tale of analogies: gravitomagnetic effects, rotating sources, observers and all that
Matteo Luca Ruggiero, Davide Astesiano
Gravitoelectromagnetic analogies are somewhat ubiquitous in General Relativity, and they are often used to explain peculiar effects of Einstein's theory of gravity in terms of fami…
Can General Relativity play a role in galactic dynamics?
Davide Astesiano, Matteo Luca Ruggiero
We use the gravitoelectromagnetic approach to the solutions of Einstein's equations in the weak-field and slow-motion approximation to investigate the impact of General Relativity…
Galactic dark matter effects from purely geometrical aspects of General Relativity
Davide Astesiano, Matteo Luca Ruggiero
We study disc galaxies in the framework of General Relativity to focus on the possibility that, even in the low energy limit, there are relevant corrections with respect to the pur…
