Reconstructing ACT-compatible and GW170817-compatible Einstein-Gauss-Bonnet Inflation from the Observational Indices
V. K. Oikonomou
In this work we use an inverse reconstruction technique for constructing ACT-compatible and GW170817-compatible Einstein-Gauss-Bonnet inflationary theories. From a given tensor-to-…
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…
Kinetic Axion Dark Matter in String Corrected Gravity
V. K. Oikonomou, F. P. Fronimos, Pyotr Tsyba +1
Under the main assumption that the axion scalar field mainly composes the dark matter in the Universe, in this paper we shall extend the formalism of kinetic axion gravity to…
Probing our Universe's Past Using Earth's Geological and Climatological History and Shadows of Galactic Black Holes
V. K. Oikonomou, Pyotr Tsyba, Olga Razina
In this short review, we discuss how Earth's climatological and geological history and also how the shadows of galactic black holes might reveal our Universe's past evolution. Spec…
Kinetic Axion Gravity Inflation
V. K. Oikonomou
In this work we investigate the quantitative effects of the misalignment kinetic axion on inflation. Due to the fact that the kinetic axion possesses a large kinetic energy w…
Gravity Phase Space in the Presence of Thermal Effects
V. K. Oikonomou, F. P. Fronimos, N. Th. Chatzarakis
In this paper, we shall consider gravity and its cosmological implications, when an extra matter term generated by thermal effects is added by hand in the Lagrangian. We for…
The Phase Space of -Essence Gravity Theory
V. K. Oikonomou, N. Chatzarakis
Among the remaining viable theories that can successfully describe the late-time era is the -Essence theory and in this work we study in detail the phase space of -Essence $f…
