Cosmological Stealth fields and Non-Equilibrium thermodynamics
Gilberto Aguilar-Pérez, Cuauhtemoc Campuzano, Víctor H. Cárdenas +2
We investigate the connection between cosmological stealth scalar fields and non-equilibrium thermodynamics in a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) backgroun…
Revealing evolution of Dark Energy density from observations
José Blanco, Víctor H. Cárdenas, Cuauhtémoc Campuzano
We present a model--independent reconstruction of the normalized dark energy density function, , derived directly from the DES-SN…
Non-geometrical perturbation on homogeneous stealth dust
José Blanco, Cuauhtemoc Campuzano, J. C. Corona-Oran +1
In this work, we study a non-geometrical perturbation to the stealth field, which means the background remains invariant. The stealh is homogeneous in a universe whose source is du…
Hamilton-Jacobi framework for Regge-Teitelboim gravity
A. Aguilar-Salas, C. Campuzano, E. Rojas
We discuss the Hamilton-Jacobi formalism for brane gravity described by the Regge-Teitelboim model, in higher co-dimension. Being originally a second-order in derivatives singular…
Stealth's cosmologies
Abigail Alvarez, Cuauhtemoc Campuzano, Víctor Cárdenas +1
We present a novel approach to construct cosmological models endowed with a particular scalar field, the stealth. The model is constructed by studying a scalar field no-minimally c…
Stealths on -dimensional dilatonic gravity
Abigail Alvarez, Cuauhtemoc Campuzano, Miguel Cruz +2
We study gravitational stealth configurations emerging on a charged dilatonic -D black hole spacetime. We accomplish this by considering the coupling of a non-minimally scal…
