The function q(z) as a consistency check for cosmological parameters

M. L. Bedran

In the Friedmann cosmology the deceleration of the expansion q plays a fundamental role. We derive the deceleration as a function of redshift $q (z)$ in two scenarios: $Λ$ CDM model…

Solving Einstein Field Equations in Observational Coordinates with Cosmological Data Functions: Spherically Symmetric Universes with Cosmological Constant

M. E. Araujo, W. S. Stoeger, R. C. Arcuri +1

Extending the approach developed by Araújo and Stoeger [1] and improved in Araújo {\it et al} [2], we have shown how to construct dust-filled $Λ \neq = 0$ Friedmann-Lema\^ıtre-Roberts…
