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 $\Lambda \ne 0$ Friedmann-Lema\^ıtre-Roberts…
