Generic slow-roll and non-gaussianity parameters in theories
Tays Miranda, Celia Escamilla-Rivera, Oliver F. Piattella +1
In this paper we establish \textit{formulae} for the inflationary slow-roll parameters , and as functions of the Ricci scalar for theories of gravity. As exam…
Inflaton candidates: from string theory to particle physics
K. Sravan Kumar
Cosmic inflation is the cornerstone of modern cosmology. In particular, following the Planck mission reports presented in 2015 regarding cosmic microwave background (CMB), there is…
Modified gravity for surveys
Luisa G. Jaime, Mariana Jaber, Celia Escamilla-Rivera
We present a new parameterization for the equation of state (EoS) , which can reproduce a -like evolution with a precision between over the numer…
Fluctuations of gravitational waves in Eddington inspired Born-Infeld theory
Celia Escamilla-Rivera
In this paper we review the EiBI gravity in the presence of a cosmological constant and its tensor perturbations analysis. We show the existence of gravitational waves in the past-…
Cosmological analysis of a DGP stable model with observations a revision
Gabriela Bárcenas-Enríquez, Celia Escamilla-Rivera, Miguel A. Garcia-Aspeitia
In this paper, we will present a Dvali-Gabadadze-Porrati stable model in order to perform an observational test using data and radial BAO scale in the galaxy distribution. I…
