gravity, which results to particularly elegant, functionally simple and transparent gravitational …

[HTML][HTML] Swampland implications of GW170817-compatible Einstein-Gauss-Bonnet gravity

SD Odintsov, VK Oikonomou - Physics Letters B, 2020 - Elsevier
Abstract We revisit the Einstein-Gauss-Bonnet theory in view of the GW170817 event, which
compels that the gravitational wave speed is equal to c T 2= 1 in natural units. We use an …

[HTML][HTML] Inflationary phenomenology of Einstein Gauss-Bonnet gravity compatible with GW170817

SD Odintsov, VK Oikonomou - Physics Letters B, 2019 - Elsevier
In this work we shall study Einstein Gauss-Bonnet theories and we investigate when these
can have their gravitational wave speed equal to the speed of light, which is unity in natural …

Inflationary dynamics and swampland criteria for modified Gauss-Bonnet gravity compatible with GW170817

Reviving non-minimal Horndeski-like theories after GW170817: kinetic coupling corrected Einstein–Gauss–Bonnet inflation

VK Oikonomou, FP Fronimos - Classical and Quantum Gravity, 2020 - iopscience.iop.org
After the recent GW170817 event of the two neutron stars merging, many string corrected
cosmological theories confronted the non-viability peril. This was due to the fact that most of …

Primordial gravitational waves predictions for GW170817-compatible Einstein–Gauss–Bonnet theory

VK Oikonomou - Astroparticle Physics, 2022 - Elsevier
In this work we shall calculate in detail the effect of an GW170817-compatible Einstein–
