Galactic Dynamics in General Relativity: the Role of Gravitomagnetism
Matteo Luca Ruggiero, Antonello Ortolan, Clive C. Speake
It is a well known fact that, in the absence of Dark Matter, the observation of the rotation curves of galaxies cannot be explained in terms of Newtonian gravity. Rotation curves b…
A note on the gravitoelectromagnetic analogy
Matteo Luca Ruggiero
We discuss the linear gravitoelectromagnetic approach used to solve Einstein equations in the weak-field and slow-motion approximation, which is a powerful tool to explain, by anal…
Geometric approach to the definition of emission coordinates
Matteo Luca Ruggiero, Angelo Tartaglia, Lorenzo Casalino
We investigate a relativistic positioning system where the coordinates of the users are determined by the proper times broadcasted by clocks in motion in spacetime: these are the s…
Gravitomagnetic resonance and gravitational waves
Matteo Luca Ruggiero, Antonello Ortolan
We show that using Fermi coordinates it is possible to describe the gravitational field of a wave using a gravitoelectromagnetic analogy. In particular, we show that using this app…
Perturbations of the orbital elements due to the magnetic-like part of the field of a plane gravitational wave
Lorenzo Iorio, Matteo Luca Ruggiero
We focus on the secular changes of the orbital elements of a planet in the solar system, determined by the magnetic-like part of a gravitational wave field. Using Fermi coordinates…
From Kerr to Heisenberg
Angelo Tartaglia, Matteo Luca Ruggiero
In this paper we consider the space-time of a charged mass endowed with an angular momentum. The geometry is described by the exact Kerr-Newman solution of the Einstein equations.…
Gravitational waves physics using Fermi coordinates: a new teaching perspective
Matteo Luca Ruggiero
The detection of gravitational waves is possible thanks to a multidisciplinary approach, involving different disciplines such as astrophysics, physics, engineering and quantum opti…
