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…
