Constraints on the duality relation from ACT cluster data
R. S. Gonçalves, A. Bernui, R. F. L. Holanda +1
The cosmic distance-duality relation (CDDR), , where and and are, respectively, the luminosity and the angular diameter di…
Robustness of determination at intermediate redshifts
R. F. L. Holanda, V. C. Busti, G. Pordeus da Silva
The most recent Hubble constant ( estimates from local methods (z << 1), km s Mpc, and the one from high redshifts km s$^{-1…
Cosmological constraints on galaxy cluster structure
R. F. L. Holanda, J. S. Alcaniz
Observations of galaxy clusters (GC's) are a powerful tool to probe the evolution of the Universe at . However, the determination of their real shape and structure is not comp…
Particle creation in a f(R) theory with cosmological constraints
S. H. Pereira, R. F. L. Holanda
In this paper we study the creation of super-massive real scalar particles in the framework of a modified gravity theory, with parameters constrained by observationa…
Probing cosmic opacity at high redshifts with gamma-ray bursts
R. F. L. Holanda, V. C. Busti
Probing the evolution of the universe at high redshifts with standard candles is a powerful way to discriminate dark energy models, where an open question nowadays is whether this…
