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 $z_{t}$ , which determines the onset of cosmic acceleration, in cosmological-model independent frameworks. In order to do…

Acceleration in Friedmann cosmology with torsion

S. H. Pereira, R. de C. Lima, J. F. Jesus +1

A Friedmann like cosmological model in Einstein-Cartan framework is studied when the torsion function is assumed to be proportional to a single $ϕ (t)$ function coming just from the…
