Emission vs Fermi coordinates: applications to relativistic positioning systems
Donato Bini, Andrea Geralico, Matteo Luca Ruggiero +1
A 4-dimensional relativistic positioning system for a general spacetime is constructed by using the so called "emission coordinates". The results apply in a small region around the…
A post-Keplerian parameter to test gravito-magnetic effects in binary pulsar systems
Matteo Luca Ruggiero, Angelo Tartaglia
We study the pulsar timing, focusing on the time delay induced by the gravitational field of the binary systems. In particular, we study the gravito-magnetic correction to the Shap…
On the time delay in binary systems
Angelo Tartaglia, Matteo Luca Ruggiero, Alessandro Nagar
The aim of this paper is to study the time delay on electromagnetic signals propagating across a binary stellar system. We focus on the antisymmetric gravitomagnetic contribution d…
Synchronization Gauges and the Principles of Special Relativity
Guido Rizzi, Matteo Luca Ruggiero, Alessio Serafini
The axiomatic bases of Special Relativity Theory (SRT) are thoroughly re-examined from an operational point of view, with particular emphasis on the status of Einstein synchronizat…
Gravito-electromagnetism versus electromagnetism
Angelo Tartaglia, Matteo Luca Ruggiero
The paper contains a discussion of the properties of the gravito-magnetic interaction in non stationary conditions. A direct deduction of the equivalent of Faraday-Henry law is giv…
Lorentz contraction and accelerated systems
Angelo Tartaglia, Matteo Luca Ruggiero
The paper discusses the problem of the Lorentz contraction in accelerated systems, in the context of the special theory of relativity. Equal proper accelerations along different wo…
