BARCENAS-ENRIQUEZ, G.; ESCAMILLA-RIVERA, C.  e  GARCIA-ASPEITIA, M.A.. Cosmological analysis of a Dvali-Gabadadze-Porrati stable model with H (z) observations. Rev. mex. fis. [online]. 2018, vol.64, n.6, pp.584-589.  Epub 05-Nov-2019. ISSN 0035-001X.  http://dx.doi.org/10.31349/revmexfis.64.584.

In this paper, we will present a Dvali-Gabadadze-Porrati stable model in order to perform an observational test using H(z) data and radial BAO scale in the galaxy distribution. In this vein, we study the tension between constraints on the cosmological constant 𝛬 and the crossover scale r c , which is associated with the Dvali-Gabadadze-Porrati model. Our results show that observations do not favor the DGP stable model as a possible candidate to fit the observations of the late cosmic acceleration.
