The growth factor parametrization versus numerical solutions in flat and non-flat dark energy models
A. M. Velásquez-Toribio, Júlio C. Fabris
In the present investigation we use observational data of to determine observational constraints in the plane using two different methods: the growth…

Constraints from observational data for a running cosmological constant and warm dark matter with curvature
Jhonny A. Agudelo Ruiz, Júlio C. Fabris, Alan M. Velasquez-Toribio +1
It is known than the inclusion of spatial curvature can modify the evolution of matter perturbations and affect the Large Scale Structure (LSS) formation. We quantify the effects o…

Reconstruction of the Cosmic Equation of State for High Redshift
A. M. Velasquez-Toribio, M. M. Machado, Julio C. Fabris
We investigate the possibilities of reconstructing the cosmic equation of state (EoS) for high redshift. In order to obtain general results, we use two model-independent approaches…
