Blue_Tilted_Tensor_Spectral_Index
A quick code that not only describes how the inflationary era is studied, but also manages to generate a blue tilted tensor spectral index through fine tuning.
Growth_Index_Of_Viable_F_R_Models
Constructed for the study of viable dark energy f(R) models and the extraction of the expected enhancement or suppression of gravitational waves.
Einstein-Gauss-Bonnet-Gravity
Short code which facilitates the study of the inflationary era for an arbitrary canonical scalar field model non-minimally coupled to the Gauss-Bonnet topological invariant. The study successfully describes primordial gravitational waves which propagate through spacetime with the velocity of light.
Late-Time-Cosmology-Of-Scalar-Tensor-Theories
Dedicated for evaluating various statefinders and comparing results with ΛCDM model for an arbitrary scalar-tensor theory.
Phase-Space-f-R-Gravity-In-The-Precense-of-Thermal-Effects
A brief introduction to autonomous dynamical analysis for modified gravity theories through and f(R) example.
Reheating
We provide a consistent description of the reheating era of a constrained Gauss-Bonnet model by using the same free parameters that result in a viable inflationary era. The theory predicts a propagation velocity of tensor perturbations which is equal to unity in order to be in agreement with the GW170817 event. The reheating era turns out to be viable if one considers that the effective EoS is equal to unity thus a primordial stiff matter era prior to the reheating era is predicted. In the end, a comparison between gravitational baryogenesis during the stiff matter era induced by CP violating terms containing either the Ricci scalar of the Gauss-Bonnet invariant is available.
