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…
Low-scale Mirror Standard Model Dark Matter and its Detection via Gravitational Waves and the Guitar Nebula
V. K Oikonomou
What if the dark matter Sector is truly dark, self-interacting and unreachable by terrestrial experiments? How could we find hints of such dark sector if it is experimentally unrea…
The Necessity of Multi-Band Observations of the Stochastic Gravitational Wave Background
S. D. Odintsov, V. K. Oikonomou
In this work we highlight an important perspective for the complete understanding of the stochastic gravitational background structure. The stochastic gravitational wave background…
Implications of a Scalar Field Interacting with the Dark Matter Fluid on the Primordial Gravitational Waves
V. K. Oikonomou
We consider the implications of a scalar field interacting with the dark matter fluid on the energy spectrum of the primordial gravitational waves. We choose an interaction type wh…
