Celestial mechanics in Newtonian-like gravity with variable

Felipe S. Escórcio, Júlio C. Fabris, Júnior D. Toniato +1

A Newtonian-like theory inspired by the Brans-Dicke gravitational Lagrangian has been recently proposed in Ref. arXiv:2009.04434(v4). This work demonstrates that the modified gravi…

Using cosmological perturbation theory to distinguish between General Relativity and Unimodular Gravity

Marcelo H. Alvarenga, Júlio C. Fabris, Hermano Velten

Unimodular Gravity is one of the oldest geometric gravity theory alternative to General Relativity. Essentially, it is based on the Einstein-Hilbert Lagrangian with an additional c…

Thermodynamics of AdS planar black holes and holography

Neven Bilic, Julio C. Fabris

A large AdS Schwarzschild black hole can be approximated by an AdS planar black hole. However, the temperature of a planar black hole is not well defined due to the translational i…

Brans-Dicke unimodular gravity

Alexandre M. R. Almeida, Júlio C. Fabris, Mahamadou Hamani Daouda +3

We propose a unimodular version of the Brans-Dicke theory designed with a constrained Lagrangian formulation. The resulting field equations are traceless. The vacuum solutions in t…

Black hole and wormhole solutions in Einstein-Maxwell-Scalar theory

Júlio C. Fabris, Tales A. O. Gomes, Denis C. Rodrigues

We classified and studied the charged black hole and wormhole solutions in the Einstein--Maxwell system in the presence of a massless, real scalar field. The possible existence of…

Nonconservative unimodular gravity: Gravitational waves

Júlio C. Fabris, Marcelo H. Alvarenga, Mahamadou Hamani-Daouda +1

Unimodular gravity is characterized by an extra condition with respect to General Relativity: the determinant of the metric is constant. This extra condition leads to a more restri…
