Analytical calculation of self-force effects on a scalar particle in an eccentric orbit around a Schwarzschild black hole
Salvatore Capozziello, Nicola Menadeo, Davide Usseglio
In this work, we analytically investigate the effects of the scalar self-force exerted by a massless scalar field on a particle in a slightly eccentric orbit around a Schwarzschild…

Gravitational-wave dispersion over inhomogeneous space-times: General relativity, screened theories of gravity and non-minimal dark energy
Nicola Menadeo, Serena Giardino, Miguel Zumalacárregui
Gravitational waves (GWs) are direct probes of cosmological gravity, sensitive to space-time inhomogeneities along their propagation. The presence of massive objects breaks homogen…

Gravitational wave propagation beyond General Relativity: geometric optic expansion and lens-induced dispersion
Nicola Menadeo, Miguel Zumalacárregui
The nature of gravity can be tested by how gravitational waves (GWs) are emitted, detected, and propagate through the universe. Propagation tests are powerful, as small deviations…
