Red or Blue Tensor Spectrum from GW170817-compatible Einstein-Gauss-Bonnet Theory: A Detailed Analysis
V. K. Oikonomou, Pyotr Tsyba, Olga Razina
In this work we shall prove that the tensor spectral index of the primordial tensor perturbations for GW170817-compatible Einstein-Gauss-Bonnet theories, takes the approximate simp…

Einstein-Gauss-Bonnet Cosmological Theories at Reheating and at the End of the Inflationary Era
V. K. Oikonomou, Pyotr Tsyba, Olga Razina
In this work we study the GW170817-compatible Einstein-Gauss-Bonnet theories during the reheating and the end of inflationary era. Given the scalar field potential which can…
