Diffusion in unimodular gravity: Analytical solutions, late-time acceleration, and cosmological constraints
Cristóbal Corral, Norman Cruz, Esteban González
Unimodular gravity is an appealing approach to address the cosmological constant problem. In this scenario, the vacuum energy density of quantum fields does not gravitate and the c…
Luminal Propagation of Gravitational Waves in Scalar-tensor Theories: The Case for Torsion
José Barrientos, Fabrizio Cordonier-Tello, Cristóbal Corral +4
Scalar-tensor gravity theories with a nonminimal Gauss-Bonnet coupling typically lead to an anomalous propagation speed for gravitational waves, and have therefore been tightly con…
Charged Taub-NUT solution in Lovelock gravity with generalized Wheeler polynomials
Cristóbal Corral, Daniel Flores-Alfonso, Hernando Quevedo
Wheeler's approach to finding exact solutions in Lovelock gravity has been predominantly applied to static spacetimes. This has led to a Birkhoff's theorem for arbitrary base manif…
Symmetries in the SME gravity sector: A study in the first-order formalism
Y. Bonder, C. Corral
A method to find the symmetries of a theory in the first order formalism of gravity is presented. This method is applied to the minimal gravity sector of the Standard Model Extensi…
Is there any symmetry left in gravity theories with explicit Lorentz violation?
Yuri Bonder, Cristóbal Corral
It is well known that a theory with explicit Lorentz violation is not invariant under diffeomorphisms. On the other hand, for geometrical theories of gravity, there are alternative…
Static and rotating black strings in dynamical Chern-Simons modified gravity
Adolfo Cisterna, Cristóbal Corral, Simón del Pino
Four-dimensional homogeneous static and rotating black strings in dynamical Chern-Simons modified gravity, with and without torsion, are presented. Each solution is supported by a…
