Solution for cosmological observables in the Starobinsky model of inflation
Gabriel German, Juan Carlos Hidalgo, Luis E. Padilla
This paper focuses on the Starobinsky model of inflation. We derive solutions for various cosmological observables, such as the scalar spectral index , the tensor-to-scalar ra…
Constraining inflationary potentials with inflaton PBHs
Luis E. Padilla, Juan Carlos Hidalgo, Gabriel German
If, after primordial inflation, the universe undergoes a relatively long reheating period, it could present a phase of matter domination supported by the oscillating inflaton field…
Bayesian analysis for a class of -attractor inflationary models
Francisco X. Linares Cedeño, Gabriel German, Juan Carlos Hidalgo +1
We perform a Bayesian study of a generalization of the basic -attractor T model given by the potential whe…
Model independent bounds for the number of -folds during the evolution of the universe
G. German, R. Gonzalez Quaglia, A. M. Moran Colorado
We present a simple procedure to obtain universal bounds for quantities of cosmological interest, such as the number of -folds during inflation, reheating, and radiation, as wel…
Production of PBHs from inflaton structure
Juan Carlos Hidalgo, Luis E. Padilla, Gabriel German
At times prior to Big Bang Nucleosynthesis, the universe could show a primordial structure formation period if dominated by a fast oscillating inflaton field during reheating. In t…
A comparison between the Jordan and Einstein Frames in Brans-Dicke theories with torsion
R. Gonzalez Quaglia, Gabriel German
In recent years, gravitational models motivated by quantum corrections to gravity which introduce higher order terms like or terms in which the Riemann tensor is not symmet…
