Primordial Gravitational Waves Predictions for GW170817-compatible Einstein-Gauss-Bonnet Theory
V. K. Oikonomou
In this work we shall calculate in detail the effect of an GW170817-compatible Einstein-Gauss-Bonnet theory on the energy spectrum of the primordial gravitational waves. The spectr…
Generalized Horndeski-Like Einstein Gauss-Bonnet Inflation with Massless Primordial Gravitons
V. K. Oikonomou, F. P. Fronimos
In this work we shall introduce a theoretical framework comprised by a non-minimal coupled canonical scalar field, a non-minimal coupling to the Gauss-Bonnet invariant and a non-mi…
Causal Limit of Neutron Star Maximum Mass in Gravity in View of GW190814
A. V. Astashenok, S. Capozziello, S. D. Odintsov +1
We investigate the causal limit of maximum mass for stars in the framework of gravity. We choose a causal equation of state, with variable speed of sound, and with the transi…
Neutron Stars Phenomenology with Scalar-tensor Inflationary Attractors
S. D. Odintsov, V. K. Oikonomou
In this work we shall study the implications of a subclass of -models cosmological attractors, namely of -attractors, on hydrodynamically stable slowly rotating neutron stars…
Dark Energy and Cosmological Horizon Thermal Effects
Artyom V. Astashenok, Sergei D. Odintsov, Vasilis K. Oikonomou
We investigate various dark energy models by taking into account the thermal effects induced from Hawking radiation on the apparent horizon of the Universe, for example near a fini…
GW170817-compatible Constant-roll Einstein-Gauss-Bonnet Inflation and Non-Gaussianities
S. D. Odintsov, V. K. Oikonomou, F. P. Fronimos +1
In this paper we investigate the inflationary phenomenology of an Einstein-Gauss-Bonnet theory compatible with the GW170817 event, by imposing the constant-roll evolution on the sc…
