Distance duality relation in symmetric teleparallel gravity
Rocco D'Agostino
In this work, we investigate the distance duality relation (DDR) in symmetric teleparallel theories, where gravity is mediated by nonmetricity. Starting from the general metric-aff…
Observational constraints on nonlocal black holes via gravitational lensing
Rocco D'Agostino, Vittorio De Falco
In this paper, we study the gravitational lensing around the static and spherically symmetric DD black holes, which we recently derived as perturbations of the Schwarzschild geomet…
Gravitational perturbations of nonlocal black holes
Rocco D'Agostino, Vittorio De Falco
We derive the master equations governing axial and polar gravitational perturbations of a generic static and spherically symmetric black hole spacetime within the framework of the…
From minimal-length quantum theory to modified gravity
Rocco D'Agostino, Pasquale Bosso, Giuseppe Gaetano Luciano
In this work, we consider generalized uncertainty principles (GUPs) that incorporate a minimal length through generic momentum-dependent deformation functions. We thus develop a sy…
Quasinormal modes of nonlocal gravity black holes
Rocco D'Agostino, Vittorio De Falco
We present a comprehensive study of the quasinormal modes of a new class of nonlocal static and spherically symmetric black hole (BH) solutions within the framework of the revised…
Distinguishing Distance Duality breaking models using electromagnetic and gravitational waves measurements
Chiara De Leo, Matteo Martinelli, Rocco D'Agostino +2
Several assumptions at the foundation of the standard cosmological model have as a direct consequence a specific relation between cosmological distances, known as the distance dual…
Black hole solutions in the revised Deser-Woodard nonlocal theory of gravity
Rocco D'Agostino, Vittorio De Falco
We consider the revised Deser-Woodard model of nonlocal gravity by reformulating the related field equations within a suitable tetrad frame. This transformation significantly simpl…
Nonlocal gravity in a proper tetrad frame: traversable wormholes
Rocco D'Agostino, Vittorio De Falco
We investigate the revised Deser-Woodard model of nonlocal gravity involving four auxiliary scalar fields, introduced to explain the standard cosmological background expansion hist…
Lagrangian formulation of the Tsallis entropy
Rocco D'Agostino, Giuseppe Gaetano Luciano
We investigate the gravitational origin of the Tsallis entropy, characterized by the nonadditive index . Utilizing Wald's formalism within the framework of modified theor…
