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 (…
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…
Two Kerr black holes with axisymmetric spins: An improved Newtonian model for the head-on collision and gravitational radiation
Marcelo E. Araujo, Patricio S. Letelier, Samuel R. Oliveira
We present a semi-analytical approach to the interaction of two (originally) Kerr black holes through a head-on collision process. An expression for the rate of emission of gravita…
