Testing the cosmic distance duality with X-ray gas mass fraction and supernovae data
R. S. Goncalves, R. F. L. Holanda, J. S. Alcaniz
In this paper we discuss a new cosmological model-independent test for the cosmic distance duality relation (CDDR), , where and $D_{L}(…

Probing the Cosmic Distance Duality Relation with the Sunyaev-Zeldovich Effect, X-rays Observations and Supernovae Ia
R. F. L. Holanda, J. A. S. Lima, M. B. Ribeiro
The angular diameter distances toward galaxy clusters can be determined with measurements of the Sunyaev-Zel'dovich effect and X-ray surface brightness combined with the validity o…

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…
