Are Galaxy Clusters Suggesting an Accelerating Universe?
J. A. S. Lima, R. F. L. Holanda, J. V. Cunha
The present cosmic accelerating stage is discussed through a new kinematic method based on the Sunyaev- Zel'dovich effect (SZE) and X-ray surface brightness data from galaxy cluste…
Constraining H0 in General Dark Energy Models from Sunyaev-Zeldovich/X-ray Technique and Complementary Probes
R. F. L. Holanda, J. V. Cunha, L. Marassi +1
In accelerating dark energy models, the estimates of H0 from Sunyaev-Zel'dovich effect (SZE) and X-ray surface brightness of galaxy clusters may depend on the matter content (Omega…
Testing the Distance-Duality Relation with Galaxy Clusters and Type Ia Supernovae
R. F. L. Holanda, J. A. S. Lima, M. B. Ribeiro
In this letter we propose a new and model-independent cosmological test for the distance-duality (DD) relation, η=D_{L}(z)(1+z)^{-2}/D_{A}(z)=1, where D_{L} and D_{A} are, respecti…
Cosmic Distance Duality Relation and the Shape of Galaxy Clusters
R. F. L. Holanda, J. A. S. Lima, M. B. Ribeiro
Observations in the cosmological domain are heavily dependent on the validity of the cosmic distance-duality (DD) relation, D_L(z) (1 + z)^{2}/D_{A}(z) = 1, an exact result require…
