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…
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…
New generalization of the simplest -attractor model
Gabriel German
The simplest -attractor model is given by the potential . However its generalization to the class of models of the type $V = V_0 \tanh^p (λϕ/M_{pl})…
A Natural Inflation inspired model
Gabriel German
We propose a modification of the Natural Inflation (NI) potential in such a way that the spontaneous symmetry breaking scale can take values less than one (in Planck units). Th…
