Approximations for the divergence of the local large-scale structure velocity field and its implications for Tilted Cosmology
Erick Pastén, Sebastián Gálvez, Víctor Cárdenas
We characterize the peculiar velocity field of the local large-scale structure reconstructed from the survey, by treating it as a fluid, extracting the divergence via differ…
Probing the parameters of a Schwarzschild black hole surrounded by quintessence and cloud of strings through four standard astrophysical tests
V. H. Cárdenas, Mohsen Fathi, Marco Olivares +1
In this paper, we concern about applying general relativistic tests on the spacetime produced by a static black hole associated with cloud of strings, in a universe filled with qui…
Studies on dark energy evolution
Daniela Grandon, Victor H. Cardenas
In this work we explore signatures of evolution for the dark energy density using latest observations on SNIa and H(z). The models consist of parametriza…
Interacting dark matter and cosmic acceleration
Victor H. Cardenas, Samuel Lepe
We study the effect of an explicit interaction between two scalar fields components describing dark matter in the context of a recent proposal framework for interaction. We find th…
Dark energy and Dark matter interaction in light of the second law of thermodynamics
Víctor H. Cárdenas, Daniela Grandón, Samuel Lepe
In the context of thermodynamics we discuss the way inevitable emerge an interaction between dark components, and in this way, provide a mechanism to understand the limits of the L…
Reconstruction of a kinetic k--essence Lagrangian from a modified of dark energy equation of state
V. H. Cárdenas, N. Cruz, Sebastián Muñoz +1
In this paper the Lagrangian density of a purely kinetic k--essence that models the behavior of dark energy described by four parameterized equations of state proposed by Cooray \&…
