A thermodynamic point of view on dark energy models
Vincenzo F. Cardone, Ninfa Radicella, Antonio Troisi
We present a conjugate analysis of two different dark energy models investigating both their agreement with recent data and their thermodynamical properties. The successful match w…
Constraining the Schwarzschild-de Sitter Solution in Models of Modified Gravity
Lorenzo Iorio, Matteo Luca Ruggiero, Ninfa Radicella +1
The Schwarzschild-de Sitter (SdS) solution exists in the large majority of modified gravity theories, as expected, and in particular the effective cosmological constant is determin…
Constraining f(T) gravity in the Solar System
Lorenzo Iorio, Ninfa Radicella, Matteo Luca Ruggiero
In the framework of theories of gravity, we solve the field equations for , in the weak-field approximation and for spherical symmetry spacetime. Since $f(T)=…
Weak-Field Spherically Symmetric Solutions in gravity
Matteo Luca Ruggiero, Ninfa Radicella
We study weak-field solutions having spherical symmetry in gravity; to this end, we solve the field equations for a non diagonal tetrad, starting from Lagrangian in the form…
Kantowski-Sachs Universes sourced by a Skyrme fluid
Luca Parisi, Ninfa Radicella, Gaetano Vilasi
The Kantowski-Sachs cosmological model sourced by a Skyrme field and a cosmological constant is considered in the framework of General Relativity. Assuming a constant radial profil…
Constraints on Covariant Horava-Lifshitz Gravity from frame-dragging experiment
Ninfa Radicella, Gaetano Lambiase, Luca Parisi +1
The effects of Horava-Lifshitz corrections to the gravito-magnetic field are analyzed. Solutions in the weak field, slow motion limit, referring to the motion of a satellite around…
