Finding a Spherically Symmetric Cosmology from Observations in Observational Coordinates -- Advantages and Challenges
M. E. Araujo, W. R. Stoeger
One of the continuing challenges in cosmology has been to determine the large-scale space-time metric from observations with a minimum of assumptions -- without, for instance, assu…
Using Time Drift of Cosmological Redshifts to find the Mass-Energy Density of the Universe
M. E. Araujo, W. R. Stoeger
In this paper we show that the mass-energy density of the Universe can be fully determined in terms of the cosmological redshifts, their time drifts and angular-diameter distance (…
Obtaining the Time Evolution for Spherically Symmetric Lemaître-Tolman-Bondi Models Given Data on Our Past Light Cone
M. E. Araujo, W. R. Stoeger
A rigorous demonstration that given appropriate data on our past light cone leads to the determination of the metric functions and all their time derivatives on our past light cone…
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 Friedmann-Lema\^ıtre-Roberts…
Perturbed Spherically Symmetric Dust Solution of the Field Equations in Observational Coordinates with Cosmological Data Functions
Marcelo E. Araujo, Sandra R. M. M. Roveda, William R. Stoeger
Using the framework for solving the spherically symmetric field equations in observational coordinates given in Araujo and Stoeger (1999), their formulation and solution in the per…
The Limits on Cosmological Anisotropies and Inhomogeneities from COBE Data
William Stoeger, Marcelo Araujo, Tim Gebbie
Assuming that the cosmological principle holds, Maartens, Ellis and Stoeger (MES) recently constructed a detailed scheme linking anisotropies in the cosmic background radiation (CM…
