From Hubble to Snap Parameters: A Gaussian Process Reconstruction
J. F. Jesus, D. Benndorf, S. H. Pereira +1
By using recent and SNe Ia data, we reconstruct the evolution of kinematic parameters , , jerk and snap, using a model-independent, non-parametric method, namely…
Gaussian Processes Reconstruction of the Dark Energy Potential
J. F. Jesus, R. Valentim, A. A. Escobal +2
Scalar Fields (SF) have emerged as natural candidates for dark energy as quintessential or phantom fields, as they are the main ingredient of inflation theories. Instead of assumin…
Determination of the Kinematic Parameters from SNe Ia and Cosmic Chronometers
D. Benndorf, J. F. Jesus, S. H. Pereira
In this work, by assuming a spatially flat Universe, we have tested 8 kinematic parametrization models with data from Cosmic Chronometers and SNe Ia from Pantheon compilatio…
Can dark matter-dark energy interaction alleviate the Cosmic Coincidence Problem?
J. F. Jesus, A. A. Escobal, D. Benndorf +1
In this paper we study a model of interacting dark energy - dark matter where the ratio between these components is not constant, changing from early to late times in such a way th…
