Energy extraction from NED-deformed rotating black holes via the Comisso-Asenjo reconnection process
Marco Figliolia, Gaetano Lambiase, Ali Övgün +1
We study rotating black holes in general relativity coupled to nonlinear electrodynamics (NED), focusing on an axisymmetric solution with deformation parameter . On the spherica…
Echoes of a hairy black hole from gravitational decoupling
Yi Yang, Ali Ovgun, Gaetano Lambiase +2
We study axial gravitational perturbations of a hairy black hole constructed within the framework of gravitational decoupling and investigate the geometric origin of echo-like late…
Confronting dark energy in Harada's Conformal Killing Gravity with observational data
Mohsen Khodadi, Gaetano Lambiase, Javad. T. Firouzjaee
Based on a comprehensive analysis of recent observational data-a combination of DESI DR1, Planck CMB, and Pantheon+ SN Ia-this study critically evaluates the two dark energy (DE) p…
Bounds on screened dark energy from near-Earth space-based measurements
Fabiano Feleppa, Welmoed Marit de Graaf, Philippe Brax +1
We test screened dark energy with near-Earth, space-based measurements. In a post-Newtonian framework, we compute leading corrections to geodetic precession (Gravity Probe B), LAGE…
Primordial observables of explicit diffeomorphism violation in gravity
Mohsen Khodadi, Nils A. Nilsson, Gaetano Lambiase +1
We investigate the potential for current and future gravitational-wave detectors to observe imprints of explicit diffeomorphism violation in primordial signals. Starting from a sim…
Charge constraint on M87* with twisted light
Fabiano Feleppa, Fabrizio Tamburini, Gaetano Lambiase
We propose a novel method to constrain the electric charge of the supermassive black hole M87* by analyzing the orbital angular momentum content of the light it emits. By leveragin…
Imprints of screened dark energy on nonlocal quantum correlations
Fabiano Feleppa, Gaetano Lambiase, Sunny Vagnozzi
We investigate how screening mechanisms, reconciling light scalar fields driving cosmic acceleration with local fifth force constraints, can be probed via their impact on non-local…
