Accessing the Acceleration of the Universe with Sunyaev-Zel'dovich and X-ray Data from Galaxy Clusters
R. F. L. Holanda, J. A. S. Lima, J. V. Cunha
By using exclusively the Sunyaev-Zel'dovich effect and X-ray surface brightness data from 25 galaxy clusters in the redshift range 0.023< z < 0.784 we access cosmic acceleration em…
CDM Accelerating Cosmology as an Alternative to LCDM model
J. A. S. Lima, J. F. Jesus, F. A. Oliveira
A new accelerating cosmology driven only by baryons plus cold dark matter (CDM) is proposed in the framework of general relativity. In this model the present accelerating stage of…
Note on Solving for the Dynamics of the Universe
J. A. S. Lima
In a recent article, Faraoni proposed an alternative procedure to solve the Friedman-Lemaitre-Robertson-Walker (FLRW) cosmological equations. The basic result of that paper was obt…
Inflationary Models Driven by Adiabatic Matter Creation
L. R. W. Abramo, J. A. S. Lima
The flat inflationary dust universe with matter creation proposed by Prigogine and coworkers is generalized and its dynamical properties are reexamined. It is shown that the starti…
