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 in two scenarios: CDM model…

On the back reaction of gravitational and particle emission and absorption from straight thick cosmic strings: A toy model
M. L. Bedran, E. M. de Sá, Anzhong Wang +1
The emission and absorption of gravitational waves and massless particles of an infinitely long straight cosmic string with finite thickness are studied. It is shown in a general t…

Taub's plane-symmetric vacuum spacetime revisited
M. L. Bedran, M. O. Calvao, I. Damiao Soares +1
The gravitational properties of the {\em only} static plane-symmetric vacuum solution of Einstein's field equations without cosmological term (Taub's solution, for brevity) are pre…
