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…
