A unique equation of state for the universe evolution from AdS space-time
M. M. Lapola, P. H. R. S. Moraes, W. de Paula +3
We apply the Induced Matter Model to a five-dimensional metric. For the case with null cosmological constant, we obtain a solution able to describe the radiation-dominated era of t…
Gaussian Process Estimation of Transition Redshift
J. F. Jesus, R. Valentim, A. A. Escobal +1
This paper aims to put constraints on the transition redshift , which determines the onset of cosmic acceleration, in cosmological-model independent frameworks. In order to do…
Kinematic Constraints on Spatial Curvature from Supernovae Ia and Cosmic Chronometers
J. F. Jesus, R. Valentim, P. H. R. S. Moraes +1
An approach to estimate the spatial curvature from data independently of dynamical models is suggested, through kinematic parameterizations of the comoving distance ($D_{C}(z…
Thermodynamic constraints on matter creation models
R. Valentim, J. F. Jesus
Entropy is a fundamental concept from Thermodynamics and it can be used to study models on context of Creation Cold Dark Matter (CCDM). From conditions on the first (…
