Recombination Thickness as an Uncertainty in Inflationary Observables
V. K. Oikonomou
Standard CMB analysis assumes a direct deterministic mapping between the multipole probed by the CMB and the primordial wavenumber . Since the recombination era has a fin…

Towards Model Agnostic Gravity Inflation
V. K. Oikonomou
In this work we construct a formalism that can reveal the general characteristics of classes of viable inflationary theories. The assumptions we make is that the slow-roll e…

Rescaled Einstein-Gauss-Bonnet Gravity Inflation
V. K. Oikonomou, Ardit Gkioni, Iason Sdranis +2
We study the inflationary phenomenology of a rescaled Einstein-Gauss-Bonnet gravity. In this framework, the gravitational constant of the Einstein-Hilbert term is rescaled due to e…
