Bayesian analysis of $I^\pm$ -Starobinsky model with Planck, ACT and DESI data

Karim Carrion, Francisco X. Linares CedeÃ±o, Gabriel GermÃ¡n +1

We present a joint Bayesian analysis to impose constraints on the generalized $I^\pm$ -Starobinsky inflationary model using the high-precision cosmological datasets: Planck, CMB lensin…

Viability of generalized $I^\pm$ -inflation from Planck, ACT, and DESI Data

Gabriel German, Juan Carlos Hidalgo

We study inflationary constraints from reheating on two classes of single-field inflationary models: a generalized $I^\pm$ -attractor with potential $V(Ï) = V_0 \!\left(1 - \sech^p\!\…

Perturbative analysis of the reheating dynamics of $I^\pm$ -attractors

Gabriel German

We study the reheating phase following inflation in the context of single-field models, focusing on the perturbative decay of the inflaton into lighter particles. A general analyti…

Reheating Dynamics in Inflationary Cosmology: Insights from $I^\pm$ -Attractor and $I^\pm$ -Starobinsky Models

Gabriel German

Reheating in inflationary cosmology is essential for understanding the early universe, influencing particle production, thermalization, and the primordial power spectrum. Crucial q…
