Primordial Cosmology of an Emergent-like Universe from Modified Gravity: Reconstruction and Phenomenology Optimization with a Genetic Algorithm
V. K. Oikonomou, Gregory K. Kafanelis
In this work we consider the realization of a variant emergent Universe scenario in the context of gravity. We use well-known reconstruction techniques existing in the liter…
Flat Energy Spectrum of Primordial Gravitational Waves vs Peaks and the NANOGrav 2023 Observation
V. K. Oikonomou
In this work we present several characteristic examples of theories of gravity and particle physics scenarios that may yield an observable energy spectrum of stochastic primordial…
Swampland Criteria and Constraints on Inflation in a Gravity Theory
V. K. Oikonomou, Konstantinos-Rafail Revis, Ilias C. Papadimitriou +1
In this paper, we worked in the framework of an inflationary theory, in the presence of a canonical scalar field. More specifically, the gravity. The valu…
Static Neutron Stars Perspective of Quadratic and Induced Inflationary Attractor Scalar-tensor Theories
V. K. Oikonomou
This study focuses on the static neutron star perspective for two types of cosmological inflationary attractor theories, namely the induced inflationary attractors and the quadrati…
