A Study of an Einstein Gauss-Bonnet Quintessential Inflationary Model
K. Kleidis, V. K. Oikonomou
In this paper we study a class of quintessential Einstein Gauss-Bonnet models, focusing on their early and late-time phenomenology. With regard to the early-time phenomenology, we…

Effects of Finite-time Singularities on Gravitational Waves
K. Kleidis, V. K. Oikonomou
We analyze the impact of finite-time singularities on gravitational waves, in the context of gravity. We investigate which singularities are allowed to occur during the infl…
