Fully metallic geodesic lenses as analog electromagnetic models of static and spherically symmetric gravitational fields
Enderson Falcón-Gómez, Vittorio De Falco, Kerlos Atia Abdalmalak +4
We demonstrate that a fully metallic and air-filled geodesic waveguide can be employed as an analog electromagnetic model of a static and spherically symmetric gravitational field.…
Radiative losses and radiation-reaction effects at the first post-Newtonian order in Einstein-Cartan theory
Vittorio De Falco, Emmanuele Battista, Davide Usseglio +1
Gravitational radiation-reaction phenomena occurring in the dynamics of inspiralling compact binary systems are investigated at the first post-Newtonian order beyond the quadrupole…
Analytical results for binary dynamics at the first post-Newtonian order in Einstein-Cartan theory with the Weyssenhoff fluid
Vittorio De Falco, Emmanuele Battista
The quantum spin effects inside matter can be modeled via the Weyssenhoff fluid, which permits to unearth a formal analogy between general relativity and Einstein-Cartan theory at…
Static and spherically symmetric wormholes in metric-affine theories of gravity
Vittorio De Falco, Salvatore Capozziello
We consider static and spherically symmetric wormhole solutions in extended metric-affine theories of gravity supposing that stability and traversability of these objects can be ac…
Epicyclic frequencies in the equatorial plane around stationary and axially symmetric wormhole geometries
Vittorio De Falco
Epicyclic frequencies are usually observed in X-ray binaries and constitute a powerful astrophysical mean to probe the strong gravitational field around a compact object. We consid…

Vittorio De Falco, Francesco Bajardi, Rocco D'Agostino +2
Different astrophysical methods can be combined to detect possible deviations from General Relativity. In this work, we consider a class of gravity models selected by the ex…
New trends in the general relativistic Poynting-Robertson effect modeling
Vittorio De Falco
The general relativistic Poynting-Robertson (PR) effect is a very important dissipative phenomenon occurring in high-energy astrophysics. Recently, it has been proposed a new model…
