An estimate of the dark matter density from galaxy clusters and supernovae data
R. F. L. Holanda, R. S. Gonçalves, J. E. Gonzales +1
In this paper, we discuss a model-independent way to obtain the present dark matter density parameter () by combining gas mass fraction measurements in galaxy cluster…

Cosmic homogeneity: a spectroscopic and model-independent measurement
R. S. Gonçalves, G. C. Carvalho, C. A. P. Bengaly +4
Cosmology relies on the Cosmological Principle, i.e., the hypothesis that the Universe is homogeneous and isotropic on large scales. This implies in particular that the counts of g…

Constraining dark matter-dark energy interaction with gas mass fraction in galaxy clusters
R. S. Goncalves, J. S. Alcaniz, A. Dev +1
The recent observational evidence for the current cosmic acceleration have stimulated renewed interest in alternative cosmologies, such as scenarios with interaction in the dark se…
