Constraining from Sunyaev-Zel'dovich effect, Galaxy Clusters X-ray data, and Baryon Oscillations
J. V. Cunha, L. Marassi, J. A. S. Lima
Estimates of from Sunyaev-Zel'dovich effect (SZE) and X-ray surface brightness of galaxy clusters depends on the underlying cosmology. In the current CDM flat cosmology, a…

Simplified Quartessence Cosmology
J. A. S. Lima, J. V. Cunha, J. S. Alcaniz
We propose a new class of accelerating world models unifying the cosmological dark sector (dark matter and dark energy). All the models are described by a simplified version of the…

New Constraints on the Variable Equation of State Parameter from X-Ray Gas Mass Fractions and SNe Ia
J. V. Cunha, L. Marassi, R. C. Santos
Recent measurements are suggesting that we live in a flat Universe and that its present accelerating stage is driven by a dark energy component whose equation of state may evolve i…
